Phase equilibria and magnetic studies in the ternary system Ce–Au–Sn

Abstract

The phase equilibria in the ternary system Ce–Au–Sn have been established in an isothermal section at 750°C. Experimental techniques used were optical microscopy, EPMA and X-ray powder analysis of arc-melted samples which were annealed at 750°C for 10 days and quenched to room temperature. Phase equilibria are characterized by the formation of seven ternary phases, of which only the equiatomic compound CeAuSn (CaIn 2-type) was already reported. Their crystal structures and physical properties were investigated and are presented.
