Scientists develop colossal 3D electrical anisotropy of MoAlB single crystal

Three-dimensional (3D) anisotropic functional properties of a single material (such as magnetic, electrical, thermal and optical properties, etc.) are not only conducive to the multi-use of materials, but also help to enrich the regulatory dimension of functional materials.

Researchers from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) have successfully grown 3D layered MAB-phase MoAlB single crystal and discovered colossal 3D electrical anisotropy. Related results were published in Small.

They used aluminum as a cosolvent and prepared high-quality and large-sized MoAlB single crystals. In this process, they found, unexpectedly, the huge 3D conductivity anisotropy in MoAlB single crystal, which was larger than previously reported.

According to experimental and theoretical studies, the 3D structural anisotropy of MoAlB was confirmed by single crystal X-ray diffraction and transmission electron microscopy. 3D anisotropic electronic structure and chemical bond of MoAlB were confirmed by theoretical calculation.

What is Ferrite Magnet?

https://www.maglastic.com/what-is-ferrite-magnet.html

Many people may have heard of ferrite magnet in their lives, but they don't know what they are. Today, I will give you a detailed introduction to what is ferrite magnet.

 The main raw materials of ferrite magnet include SrO or BaO and Fe2O3. Ferrite magnet is a sintered permanent magnet material composed of barium and strontium ferrite. In addition to strong anti-demagnetization performance, this magnetic material also has the advantage of low cost. The magnet of the opposite sex must be magnetized in the direction taken because it is oriented along the manufacturing direction; while the magnet of the same sex can be magnetized in any direction because it has no orientation, although a slightly stronger magnetic induction is often found on the side where the pressure is the smallest. Due to low cost, moderate performance, and good temperature resistance, ferrite magnet have a wide range of applications, from motors and speakers to toys and crafts. Therefore, it is currently the most widely used permanent magnet material.

 1. Classification of Ferrite Magnet

According to different production processes, ferrite magnet is divided into sintering and bonding. Among them, sintering is divided into dry pressing type and wet pressing type, and bonding is divided into extrusion molding, compression molding and injection molding. Injection magnets are a type of magnet that has grown rapidly in recent years due to its advantages such as low energy consumption, short molding cycle, suitable for mass production, free magnetic pole orientation, and easy molding of complex devices.

 According to whether an external magnetic field is applied during molding, it can be divided into isotropic permanent magnets and anisotropic permanent magnets. The magnetic properties of isotropic sintered ferrite magnets are weak, but they can be magnetized in different directions of the magnet; while the anisotropic ferrite magnet has strong magnetic properties, but can only be magnetized along the predetermined magnetization direction.

 The soft, elastic and twistable magnet made of bonded ferrite powder and synthetic rubber is also called rubber magnet.

 2. Performance Characteristics of Ferrite Magnet

Ferrite magnet is characterized by high coercivity and low remanence in performance. Ferrite magnet has high coercivity as well as strong anti-demagnetization ability, and is suitable for working in dynamic magnetic circuit environments with large temperature changes.

 The ferrite magnet is hard and brittle and can be cut with emery tools.

The main raw material is oxide, so it is not easy to corrode and generally does not require plating.

 Working temperature: -40℃ to +300℃.

 We hope that you can better understand what is a ferrite magnet through the above description.

Application of Neodymium Ring Magnet in Motor

The magnetic field distribution of the neodymium ring magnets is as follows: the inner space of the ring still belongs to the outer magnetic field distribution, and part of the magnetic induction line connects the magnetic poles of both ends through the inner hole of the ring.

What is the magnet?

A magnet is a substance that repels each other. If small molecules in an object can be arranged in the same direction, it becomes a magnet. Its composition is iron, cobalt, nickel and another special atomic structure, the atom itself has magnetic moments, the general arrangement of these mineral molecules is disorderly. Magnetic regions interact with each other to show no magnetism, but the direction of molecular alignment tends to be consistent under the guidance of external forces (such as magnetic field), showing magnetism, also known as a magnet.

The magnetization of magnets:

Most magnetic materials can be magnetized to saturation in the same direction, which is called “magnetization direction” (orientation direction). Magnets without orientation (also known as isotropic magnets) are much less magnetic than oriented magnets (also known as anisotropic magnets).

Advantages and disadvantages of ring magnet for motors

Ring magnets used in motors are usually bonded neodymium magnets with injection-molded ferrite rings. The disadvantage is that both materials have poor magnetic properties.

The advantage is that the cost is low, easy to assemble, and the general speed such as 5000rpm or so, no protection outside the magnet, but for the general motor is enough.

What are the advantages and disadvantages of neodymium ring magnets?

Advantages: simple structure, easy installation, and cost-saving.

Disadvantages: cost is more expensive than tile design.

Technically, the radiation ring has been very mature, and some large customers are using it in batches.

Thank you for reading our article, hope it can help you better understand the characteristics of NdFeB magnets. We, Ningbo Tengxiao Magnetic Industry Co., Ltd. have many neodymium ring magnets and custom industrial magnets products. Welcome to visit our website to check.

Rubber/Flexible Magnets

Brief introduction of rubber magnets(magnetic rubber):

Rubber magnets sometimes called magnetic rubber. Magnetic rubber itself has no magnetism , the magnetism comes from filled magnetic powder. So the magnetic powder is obligate material for produce magnetic rubber. Magnetic additive can be divided into metal magnetic powder, Fe-Co powder, Fe-Ni powder and Fe-Ba powder.  Fe-Co powder is the most widely used. Metal magnetic powder is seldom used because of the expensive cost. At the present, the Fe-O powder mostly used, they are ferric oxide and two valence metal compounds, although is the same ferrite magnetic powder, the ultimate magnetic strength are not the same because of the different crystal habit,particle size, and uniformity. In fact, rubber magnet belong to ferrite magnet series, it is the magnet composed of bond ferrite magnet powder and synthetic rubber, made out by extrusion molding and injection molding, and it can be distorted. Rubber magnets can be machined into rubber magnetic strips, rubber magnetic rolls, rubber magnetic sheets and other different shapes.

 Rubber magnet belong to ferrite magnetic materials series, it is made from ferrite magnes powder and rubber by extruding or injecting. It has properties of soft, resilience and twisable. Just because of these properties,it also called flexible magnets. It’s maximum energy is 0.60～1.50 MGOe。

 Manufacturing process of rubber magnets(magnetic rubber):

The manufacturing process of magnetic rubber is much the same as other products. At first, determine the variety,particle size and dosage of magnetic powder. Then determine the rubber kinds according to application of rubber magnets. For example, natural rubber needed for wear resistant rubber magnets. The magnetization process need to be added when vulcanize it, which give the products permanent magnetism. The advantage for magnetize it before vulcanizing is external magnetic field not changed and pass the rubber network easily；The passing ability of magnetic field is bad for magnetize it after vulcanizing, but it is easy to operate .

 The physical quantity used to represent magnetism of rubber magnets are magnetic induction strength, remanence , and maximum energy etc. Magnetic induction strength is most commonly used, the value of which is required to be 100-600GS.

 Rubber magnets made of magnetic powder（SrO6、Fe2O3),（CPE）and other additive（EBSO、DOP)，and made out by extruding or calendering. Rubber magnets can be devided into  isotropic rubber magnets and anisotropic rubber magnets . It can be machined into rubber magnetic strips, rubber magnetic rolls, rubber magnetic sheets and other different shapes. The maximum energy of rubber magnet is 0.60-1.50 MGOe. The surface of rubber magnet can be covered with PVC,coated paper,adhesive.

 Production process of rubber magnets:

ingredient→mixture→extruding/calendering /injecting → machining →magnetizing →inspecting(appearance,size,magnetism,hardness,density, ageing resistance etc) → packing

 The application of rubber magnets:

The door sealing strip is on behalf of the traditional application of rubber magnets. With the development of high-tech and household electrical appliance, rubber magnets get more widely used.The main application field of rubber magnets are micro-motors,door sealing for kinds of electrical appliances and advertisement.

How to distinguish bonded NdFeB and sintered NdFeB?

Neodymium magnets can be called neodymium iron boron magnets, which is a general term for powerful magnets. Its chemical formula is Nd2Fe14B. It is an artificial permanent magnet and has the strongest magnetic force so far. The material grades of neodymium iron boron magnets are N35-N52; the shapes can be processed into different shapes according to specific requirements, including round, square, perforated, magnetic tile, magnetic rod, convex or trapezoidal, etc.

How to distinguish bonded NdFeB and sintered NdFeB? In fact, both types of magnets belong to NdFeB. The two types of magnets are distinguished according to their production processes. The bonded NdFeB magnet is actually formed by injection molding, while the sintered NdFeB magnet is formed by evacuating and then heating at high temperature.

Bonded neodymium iron boron magnets are formed by injection molding, so they contain adhesives, the density of which is generally only 80% of the theoretical. The sintered NdFeB magnet is heated at a high temperature through a complicated process. Therefore, the bonded NdFeB magnet is attenuated by about 30% compared with the sintered NdFeB magnet.

Sintered NdFeB magnet is an anisotropic magnet produced by powder sintering method. Generally, only a blank can be produced through sintering, and then through mechanical processing (such as wire cutting, slicing, grinding, etc.) to become magnets of various shapes. Sintered NdFeB is a hard and brittle material that is difficult to process. It has high loss during processing, high cost, poor dimensional accuracy, poor corrosion resistance, and the surface needs to be electroplated. But the advantage is that the performance is higher, and it has achieved more than 50M.

In summary, the magnetic properties of bonded NdFeB magnets are only about 5% of that of sintered. At present, the energy product of sintered NdFeB magnets can reach more than 50M, while the bonded magnets are generally below 10M, and the best is only 12M. The performance of the magnetic powder used in bonded magnets is generally 15M, and it is only 10.5M at most after being made into bonded magnets. Therefore, sintered NdFeB is generally used in a wider range than bonded NdFeB.

 Magnetization Of Neodymium Magnets

All Neodymium magnets are anisotropic and oriented with a preferred direction during production, they can only be magnetized thru the oriented direction. Disc/cylinder/ring magnets are axially or diametrically magnetized, block magnets are magnetized along one side of three sides, arc segment magnets are generally diametrically magnetized.
