The PrSi compound undergoes a second-order ferromagnetic-to-paramagnetic transition at the Curie temperature of Tc = 52 K. Large MCE with no magnetic hysteresis loss is observed around Tc. The maximum values of magnetic entropy change （△S） are found to be -8.6 and -15.3 J.kg^-1.K^-1 for the magnetic field changes of 0-2 T and 0-5 T, respectively. The large △S with no hysteresis makes PrSi compound a competitive candidate for magnetic refrigerant.展开更多
