Abstract

Abstract

The reversible change and irreversible change in coercivity and mioros-tructure for sintered SmCo₅ and Sm(Co, Cu, Fe, Zr)7.0 alloy were studied by magnetic measurement, transmission electron microscopy (TEM) and X-ray diffractions.The causes which lead to these reversible changes have be en discussed.
