Description

technical field

[0001] The invention belongs to the field of magnetic materials, and relates to a soft magnetic material and a preparation method thereof, an amorphous strip, a soft magnetic tape and a soft magnetic sheet, in particular to an amorphous nanocrystalline soft magnetic material, a preparation method and application thereof, and an amorphous strip , Amorphous and nanocrystalline ribbons and amorphous and nanocrystalline magnetic sheets. Background technique

[0002] Soft magnetic materials are a kind of commonly used functional materials that are easy to magnetize and demagnetize. They have excellent magnetic application characteristics such as high magnetic permeability, low coercive force, small hysteresis, and low loss. They are used in industrial fields such as electric power, electronics, and motors. have wide applications. Since the 19th century, soft magnetic materials have successively developed into electrical pure iron, silicon steel, permalloy, iron-a...
