In this study, the magnetic and magnetocaloric properties of a recently elaborated La$_{0.7}$Sr$_{0.3}$Mn$_{0.95}$Fe$_{0.05}$O$_3$ perovskite manganites have been modelled using different theoretical methods based on Landau theory and phenomenological models. The calculations were done by exploring the measurement data of magnetization vs. temperature at various low and high magnetic field values. The results confirmed that this compound has a magnetic phase transition of the second-order type from ferromagnetic to paramagnetic states at Curie temperature near the room temperature. The theoretical values of the magnetic entropy change (-${\Delta}$
S $_M$) are estimated in low and high applied magnetic fields from these methods. The analysis of our obtained results of the relative cooling power indicated that this compound is a potential candidate material for magnetic refrigeration technology.
