Embodiment 1
[0016] (1) Fe 70 Si 15 B 4 Cu 0.4 m 8 Y 2.6 After the amorphous strip is kept at 420°C for 1 hour in a vacuum annealing furnace, it is mechanically crushed;
[0017] (2) Fe 70 Si 15 B 4 Cu 0.4 m 8 Y 2.6 After mechanical crushing, the amorphous thin strips are placed in a planetary ball mill for ball milling, the ball-to-material ratio is 5:1, the ball milling time is 4 hours, the speed is 260r / min, and ethanol is added to prevent oxidation. After drying, different particle sizes are obtained by sieving Fe 70 Si 15 B 4 Cu 0.4 m 8 Y 2.6 magnetic powder;
