Soft magnetic material According to Japanese “Open Patent Publication No. 60-21351” reported that Japan on February 2, 1985 announced a patent for soft magnetic materials. This soft magnetic material is a Co-Hf-Nb ternary amorphous alloy with low Hc, high μ and Bs. Alloy containing Hf1 ~ 5 (at)% (preferably 1.5 ~ 3 (at)%), containing Nb4 ~ 8 (at)%, the balance of Co. Amorphous magnetic alloy According to Japanese “Patent Publication No. 60-52544”, Japan announced March 25, 1985, an amorphous magnetic alloy. The composition of the alloy can be expressed by the following formula: (Co_ (100-y) Fe_y) _ (100-x) (Zr_ (100-W) NbW) _x. Where X = 5-10, y = 0.5-4, w = 20-90. The Co-Fe-Zr-Nb amorphous alloy has a Bs of ≧ 10000 Gs, a temperature of transition to a crystalline state of ≧ 450 ° C., an alloy
