Abstract

The system RNi//2 (R equals Dy, Ho and Er) is verified to be promising as magnetic refrigerant in the wide temperature range below 35 K. We prepared these compounds and measured the temperature variation of the specific heat and the magnetization in magnetic field up to 5 T. From these results we determine the total entropy and the magnetic entropy change by a magnetic field. It is made clear that these compounds are applicable to the magnetic refrigerants using an Ericsson-type cooling cycle below 35 K.
