摘要：
We have used the effective field theory based on probability distribution method to investigate the hysteresis behavior of a magnetic nanoparticle with core/shell morphology in a random field. The hysteresis curves are obtained for different values of the random field and the temperature. We find a number of characteristic behaviors, such as the existence of double hysteresis loops for appropriate values of the system parameters. The remanent magnetization and the coercive field as a function of the temperature are examined.
