Abstract

Specific heat of dysprosium gallium garnet (DyGaG) single crystal has been measured between 20 and 2K in the magnetic fields up to 5T. 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 one of the good materials for magnetic refrigeration between 12 and 2K.
