Abstract

The compound Ho₂ In exhibits two successive magnetic phase transitions: a spin-reorientation transition at T_SR =32 K and a magnetic-ordering transition at T_C =85 K. The maximum reversible -Δ S_M values are 6.3 and 11.2 J/kg K at T_SR and T_C, respectively, for a field change of 5 T. These two -Δ S_M peaks with the same sign are partly overlapping, which results in a wide temperature interval with appreciable magnetocaloric effect. The results on Ho₂In indicate that materials with successive SR and magnetic-ordering transitions may constitute an important new class of magnetic refrigerants since they work in a wider temperature range than the conventional refrigerant materials.
