Özet

Herein, nonequilibrium hysteresis properties of the double perovskite (DP) Sr2FeMoO6 are investigated using mean field theory and the Glauber dynamics approach within the Ising model framework. The phase region of the system is determined by analyzing the time-varying average (Formula presented.) and (Formula presented.) magnetizations. The dynamic Fe and Mo magnetizations are calculated depending on the temperature to get the dynamic transition points for different ratio of the system parameters. The effects of temperature and single-ion anisotropy on dynamic hysteresis behaviors are examined in depth. Some recognizable characteristics are discovered, such as the occurrence of a triple hysteresis loop for appropriate crystal field and temperature values. The Sr2FeMoO6 system exhibits hysteresis behavior similar to DPs such as A2FeMoO6, Sr2VMoO6, and Sr2CrWO6.
