AB  - In this work, we have investigated the magnetic and the magnetocaloric properties of polycrystalline Pr0.63A0.07Sr0.3MnO3 (A = Pr, Sm and Bi) prepared by solid-state reaction at high temperature. The magnetic study revealed that all our samples exhibit a ferromagnetic-paramagnetic transition with increasing temperature, with an important magnetocaloric effect near TC. Using theoretical calculations, we have enhanced the magnetocaloric effect for our samples, based on theoretical composites. The obtained composites exhibit important magnetocaloric effect in an extended temperature range, which indicates the possibility of using these composites for magnetic refrigeration.
