Abstract

The specific heat of dysprosium gallium garnet (DyGaG) single crystal has been measured between 20 and 2 K in magnetic fields up to 5 T. From the specific heat and adiabatic demagnetization measurements, the temperature dependence of the entropy in various magnetic fields is determined. It is shown that DyGaG is a good material for magnetic refrigeration between 12 and 2 K.
