We performed a theoretical study of the magnetic hysteresis curves for an Fe3O4-based magnetic multilayer. Such a systems are known as the spin valves in the spintronics field. To investigate the temperature dependence of the magnetization process in such a system, we extend the retarded trace method and plot the magnetic hysteresis curve by computer simulation. Our results show very good agreement with the experimental data.
