PROBLEM TO BE SOLVED: To provide an amorphous soft magnetic alloy having excellent soft magnetic properties, particularly having saturation magnetization higher than that of the conventional one, and further excellent in the thermal stability of magnetic properties. SOLUTION: An amorphous soft magnetic alloy in which the temperature spacing ΔTx of a supercooled liquid expressed by the formula of ΔTx=Tx-Tg (wherein, Tx is a crystallization starting temperature, and Tg is a glass transition temperature) is >=20K, Fe, Ga and one or more kinds of elements Q selected from P, C, Si and B are at least provided, and the main phase is composed of an amorphous phase is adopted. |
