Magnetic Properties and Magnetocaloric in Double Perovskite Oxides

We have studied the magnetic properties and magnetocaloric effect in Sr2FeMoO6 compound by using the Monte Carlo study. Thermal magnetization, M and dM/dT of Sr2FeMoO6 are investigated. The transition temperature and lock-in-transition temperatures are deduced. The temperature dependence of the magnetic entropy and of the adiabatic temperature for a several magnetic fields have been also obtained. The field dependence of relative cooling power and magnetic hysteresis cycle of Sr2FeMoO6 have been determined for a several magnetic field and temperatures. This system might be a promising base for developing the new kinds of magnetic refrigerant as working materials in magnetic refrigeration technology.
