In a wide range of fields, it can replace soft magnetic materials such as Co-based amorphous, silicon steel sheets, ferrites, and Permalloy to manufacture common-mode chokes, differential-mode filter inductors, high-frequency switching power supplies, high-frequency inverters, zero-sequence mutual inductors, magnetic amplifiers, and many other electrical components. It is also the best material for components such as high-sensitivity fidelity magnetic heads, high-performance magnetic amplifiers, and leakage protection switches.
