Magnetic alloy

特許 権利維持 An amorphous soft magnetic alloy and an inductance component using the same are provided to obtain a high-frequency magnetic core at low cost by using amorphous soft magnetic metal material with high saturation magnetic flux density and resistivity. An amorphous soft magnetic alloy has a composition expressed by a formula: (Fe1-aTMa)100-w-x-y-zPwBxLySizTipCqMnrCus, wherein inevitable impurities are contained, TM is at least one selected between Co and Ni, and L is at least one selected from a group consisting of Al, Cr, Mo, and Nb.
