| 简介 |
The present invention provides a Fe based hard magnetic alloy having a very wide temperature interval in the super-cooled liquid region, having a hard magnetism at room temperature, being able to be produced thicker than amorphous alloy thin films obtained by conventional liquid quenching methods, and having a high material strength, wherein the Fe based hard magnetic alloy comprises Fe as a major component and containing one or a plurality of elements R selected from rare earth elements, one or a plurality of elements M selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W and Cu, and B, the temperature interval DELTA Tx in the super-cooled liquid region represented by the formula of DELTA Tx = Tx - Tg (wherein Tx and Tg denote a crystallization initiation temperature and glass transition temperature, respectively) being 20 DEG C or more. |
