Research Progress and Application Prospect of ferro-based soft magnetic amorphous/nanocrystalline alloys reviewed the discovery and development history of soft magnetic amorphous alloys, introduced the important contributions of relevant basic research achievements and technological progress to the development and industrial application of ferro-based soft magnetic amorphous/nanocrystalline alloys, and pointed out the challenges and development direction in the development and application of ferro-based soft magnetic amorphous alloys. The corresponding author of the above work is Professor Yao Kefu of the School of Materials Science, Tsinghua University.
Nanocrystalline magnetic core has high permeability, high saturation magnetic induction, low coercivity and low loss. Suitable for EMC/EMI filter common mode inductor, high frequency transformer, frequency converter, current transformer and other occasions. In the field of new energy, such as solar inverter, wind power generation and other occasions has also been widely used.
Hard magnetic material: when the magnetic field is removed, can still have magnetic materials; Soft magnetic materials are materials that have high magnetic induction when the magnetization field is present and lose magnetism when the magnetization field is removed
