Abstract
Monte Carlo simulations are used to investigate the magnetic properties of the nanostructured spin-7/2 and spin-1 ferrimagnetic bilayers within interlayer exchange interactions. The effects of nonmagnetic layers thickness, magnetic coupling and the crystal field on the blocking temperature, magnetization and hysteresis loops are studied. It is found that the blocking temperature decreases when increasing the magnetic coupling between layers and/or increasing the thickness of the magnetic layer. Besides, the model exhibits multiple hysteresis loops for which the area decreases when increasing the thickness of the magnetic layer, the crystal field and/or the temperature. Moreover, the effect of temperature on the behavior of the partial and the total magnetization and the total susceptibility are also as investigated.
