Recently, the reporter learned from the Institute of Metal Research of the Chinese Academy of Sciences that the research group led by the researcher Zhang Zhidong has prepared nanocomposite rare earth permanent magnetic blocks and thin film materials, which are expected to become a new generation of rare earth permanent magnet materials in information, micromachinery, and micromotors. Other areas will have broad application prospects.
Since the third generation of rare earth permanent magnetic materials has been developed, people are still exploring new types of permanent magnet compounds with even better internal magnetic properties. Iron-based rare earth nitrides have become one of the hot spots for people to study. Zhang Zhidong’s research team led the research team in the aspects of magnetic phase transition of rare earth transition metal compounds, the mechanism of rare earth metastable phase transition to steady state, the magnetic coupling mechanism of nanocomposite magnetic materials, and the correlation between quantum well effects and magnetic interactions. Systematic in-depth research results.
