Abstract

A new alloy, having the formula, Co2ScSn, has been prepared. This is found to have the cubic Heusler L21 type structure (a = 6.19A). Magnetization measurements reveal a large drop in magnetization around 270K. Low field ac susceptibility also shows a transition at 268K which we take to be the Curie temperature of the alloy. The magnetic moment at 5K is found to be 0.55 μB per cobalt atom.119Sn Mössbauer measurements at 8K show a hyperfine split spectrum with a hyperfine field of about 40 kOe. Attempts to prepare other Co2RSn alloys particularly with R=Lu, were not successful.
