The new magnetic materials in industrial production is expected
A team of researchers at Virginia Commonwealth University announced that they synthesize a new type of magnetic material, in terms of comparable magnetic rare earth permanent magnet made of traditional materials, industrial production is expected to reduce dependence on rare earth resources. Author of the study and professor of physics at Virginia Commonwealth University School of Humanities • Shiv Khanna said the discovery opened up a new artificial materials overtake the traditional path of the new permanent magnet material. Related papers published in the latest issue of "Applied Physics Letters" on.
Cobalt and carbon nanoparticles new material made of iron nanoparticles and magnetic structure, the size of the latter two is about 5 nm. Experiments show that the magnetic material is entirely comparable to those made from rare earth can be made of conventional permanent magnet material. In addition, this material can store information at 516.85 degrees Celsius, has good heat resistance and stability, and have long-range order of the features in data storage applications also have potential applications.
Rare Earth has the "industrial vitamins" in the world, is now an extremely important strategic resources, with a wide range of applications in petroleum, chemical, metallurgy, textile and other fields. Especially those made of rare earth permanent magnet materials, for communications, electronics and automobile manufacturing industry, is essential. In addition, with the advent of green technology market and the rapid development of electric and hybrid electric vehicles, direct drive wind turbine power systems and energy storage systems market is growing, the demand for permanent magnetic materials and rare earth resources also will be increasing shortage of resources has become increasingly prominent.
