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

The phase equilibria in the ternary system Ce-Au-Sn have been established i n an isothermal section at 750 degreesC. Experimental techniques used were optical microscopy, EPMA and X-ray powder analysis of arc-melted samples wh ich were annealed at 750 degreesC for 10 days and quenched to room temperat ure. Phase equilibria are characterized by the formation of seven ternary p hases, of which only the equiatomic compound CeAuSn (CaIn2-type) was alread y reported. Their crystal structures and physical properties were investiga ted and are presented. (C) 2001 Elsevier Science B.V. All rights reserved.
