A research team at the Virginia Commonwealth University in the United States claims that they have synthesized a new type of magnetic material that is comparable in magnetic to traditional rare earth materials, and is expected to reduce dependence on rare earth resources in industrial production. Shif Kana, a professor at the Virginia Federal University's School of Physics and Humanities, who said that the discovery opened up a new path for artificial new materials to catch up with traditional permanent magnet materials. Related papers were published in the latest issue of Applied Physics Letters. This new material consists of iron nanoparticles and magnetically cobalt and carbon nanoparticles, the latter two having a size of about 5 nanometers. Experiments have shown that this material is magnetically comparable to traditional permanent magnet materials made from rare earths. In addition, this material can store information at a high temperature of 516.85 degrees Celsius, has good heat resistance and stability, and has long-range order, and has potential application value in data storage applications. Rare earth has the reputation of “industrial vitamins†and is now an extremely important strategic resource with extensive application value in petroleum, chemical, metallurgical and textile fields. In particular, permanent magnet materials made from rare earths are even more essential for industries such as telecommunications, electronics and automotive manufacturing. In addition, with the emergence and rapid development of the green technology market, the market for pure electric and hybrid electric vehicles, direct-drive wind turbine power systems and energy storage systems is growing, and the demand for permanent magnet materials and rare earth resources is also increasing. The problem of shortage of resources has become increasingly prominent. The co-author of the paper, Virginia-based Federal University postdoctoral Ahmed El-Jenty, said that this is an important finding for addressing the shortage of rare earth resources. Professor Everett Carpenter, head of the school's nanoscience and nanotechnology program, said the new material has shown many outstanding features, some of which even surpass traditional permanent magnet materials. Sichuanese food five hundred years ago relied on pepper and medlar, but the South American crop pepper was introduced, and the original recipe was rewritten. In the history of materials science, there has been repeated such "cooking" innovations, incorporating cheap materials and obtaining expensive features. With the constant innovation of materials science, the two basic "staple foods" - the status of iron and carbon - seem to be unassailable. Ideally, humans will not get stuck by material bottlenecks, and they can do all the difficult moves with the elements enriched in the earth's crust.
