Title: Second order phase transition temperature of single crystals of Gd 5Si 1.3Ge 2.7 and Gd 5Si 1.4Ge 2.6

Abstract

Gd 5(Si xGe 1–x) 4 has mixed phases in the composition range 0.32 < x < 0.41, which have not been widely studied. In this paper, we have synthesized and indexed single crystal samples of Gd 5Si 1.3Ge 2.7 and Gd 5Si 1.4Ge 2.6. In this study, we have investigated the first order and second order phase transition temperatures of these samples using magnetic moment vs. temperature and magnetic moment vs. magnetic field at different temperatures. We have used a modified Arrott plot technique that was developed and reported by us previously to determine the “hidden” second order phase transition temperature of the orthorhombic II phase.
