Abstract

PURPOSE: To prevent rare earth elements such as Sm in a rare earth elements cobalt magnet from evaporating, increase the density of the magnet to 99% or more, and improve the magnetic and mechanical properties by producing the magnet by a combination of sintering in a hydrogen atmosphere and hot hydrostatic press. treatment.
