In this paper, the magnetocaloric in La_0.5Sm_0.2Sr_0.3Mn_1-xFe_xO₃ compounds with x = 0 (LSSMO) and x = 0.05 (LSSMFO) were simulated using mean field model theory. A strong consistency was observed between the theoretical and experimental curves of magnetizations and magnetic entropy changes, $-\Delta S_M\left(T\right)$ . Based on the mean-field generated $-\Delta S_M\left(T\right)$ , the substantial Temperature-averaged Entropy Change (TEC) values reinforce the appropriateness of these materials for use in magnetic refrigeration technology within TEC (10) values of 1 and 0.57 J∙kg⁻¹∙K⁻¹under 1 T applied magnetic field.
