[0002] At present, amorphous and nanocrystalline strips are widely used in key fields such as power electronics, new energy vehicle motors, charging piles and transformers due to excellent magnetic properties, high-frequency low loss and good electromagnetic shielding characteristics, and the market demand shows a continuous growth trend. In particular, in the new energy vehicle driving system, the demand for high-performance soft magnetic materials is increasing, and amorphous and nanocrystalline materials have become important candidate materials for core components such as motor stators and rotors and magnetic cores due to their high saturation magnetic induction strength and low coercivity.
