Abstract. Certain magnetic characteristics and the hysteresis behavior of double perovskite Sr₂FeMoO₆ were analysed through Monte Carlo simulation. Our investigation shows this ferrimagnetic compound exhibits a second-order phase transition at a Curie temperature $T_C = 490$ K. The effect of the crystal field on magnetization was examined, and a phase diagram was plotted in the (crystal field, temperature) plane. Furthermore, in the presence of an external magnetic field, the influence of temperature on the hysteresis loop’s behaviour was explored.

Key words: Double perovskite Sr2FeMoO6, Magnetic properties, Monte Carlo, Curie temperature.
