Thermodynamic Properties of RZnSn₂ (R = Y, Er, Lu) Compounds with HfCuSi₂ Structure Type

Abstract:

The results of magnetic and specific heat studies are reviewed and discussed for the series of RZnSn₂ (R = Y, Er and Lu) compounds crystallizing in the same tetragonal HfCuSi₂ - type of structure. A sharp peak in the specific heat of ErZnSn₂ compound is indicative for magnetic ordering of Er moments at 5.0 K, being in agreement with its established antiferromagnetic nature. The estimated magnetic entropy S_magn contribution is less than that expected for the ground state J = 15/2 multiplet of Er³⁺.
