Abstract

Systematic investigations of binary amorphous Fe-T alloys (T=an early transition-metal elements Ti, Zr, Nb, Hf, Ta.) over wide composition ranges reveal depressed magnetic properties with anomalously low magnetic ordering temperature and magnetization. We show in this work, via a prototype amorphous Fe₇₀Ti₃₀ alloy, the substitution of Fe by Co, Ni, or Cu greatly enhances the magnetic ordering temperature and the magnetization. Our results indicate that this is primarily caused by the increased Fe moment upon alloying.
