ABSTRACT={In this communication, we report the magnetic and magnetocaloric study of Pr0.5Sr0.5MnO3 and La0.5Ca0.5MnO3 compounds prepared by solid-state reaction at high temperature. The temperature dependence of magnetization indicates that each sample displays two distinct magnetic transitions: when decreasing temperature, each sample undergoes a paramagnetic-ferromagnetic transition followed by a ferromagnetic-antiferromagnetic transition. The magnetocaloric study indicates that both samples are the seat of direct (near the paramagnetic-ferromagnetic transition) and inverse (near the ferromagnetic-antiferromagnetic transition) magnetocaloric effect. The inverse magnetocaloric effect is more important for Pr0.5Sr0.5MnO3 compound due to the absence of magnetic phase separation.}}
