The magnetocaloric effect in Pr0.5Sr0.5MnO3 (PSMO) has been successfully modeled in this work. PSMO undergoes a first-order antiferromagnetic charge ordering (AFM/CO) to a ferromagnetic (FM) transition at \( T_{CO}=T_{N}\sim 165\) K followed by a second-order ferromagnetic (FM) to paramagnetic (PM) transition at the Curie temperature, \( T_{C}\sim 255\) K. The magnetocaloric effect in PSMO has been studied by the simulation of the magnetic entropy change \( (-\Delta S_M)\) for these two transitions by developing a numerical approach based on the Landau free energy within the mean-field approximation. Simulated results agree well with the experimental ones for these two transitions.
