Abstract:
A hard magnetic alloy having soft and hard magnetic phases, the hard magnetic alloy obtained by heat treatment of a glassy alloy at a heating rate of 20.degree. C./min or more, wherein the glassy alloy contains Fe as a main component, at least one element R selected from the rare earth elements, the content of the at least one element R being no greater than 15 atomic %, at least one element M selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, and Cu, and B, and having a supercooled liquid region having a temperature width .DELTA.Tx of 20.degree. C. or more, which is represented by the equation .DELTA.Tx=Tx-Tg, wherein Tx indicates the crystallization temperature, and Tg indicates a glass transition temperature.
