Magnetic properties and magnetocaloric effects (MCEs) of the PrSi compound were studied. The PrSi compound undergoes a second-order ferromagnetic-to-paramagnetic transition at the Curie temperature of T (C) = 52 K. Large MCE with no magnetic hysteresis loss is observed around T (C). The maximum values of magnetic entropy change (Delta S) are found to be -8.6 and -15.3 J center dot kg(-1)center dot K-1 for the magnetic field changes of 0-2 T and 0-5 T, respectively. The large Delta S with no hysteresis makes PrSi compound a competitive candidate for magnetic refrigerant.
