Sintered Ce-Co-Cu-Fe-Ti magnets

Abstract

Ce(Co-Cu-Fe-Ti)z alloys were prepared with 5.6⩽z⩽7.4. They were ground into powders and sintered in Ar atmosphere. It was found that Ti enhanced coercivity and rectangularity. A permanent magnet with Br=7400 G, IHc=6100 Oe, (BH)max=13 MG Oe, and rectangular hysteresis loop was achieved on sintered samples having the composition Ce(Co0.727Fe0.12Cu0.14 Ti0.013)6.5.
