摘要：
In this paper, we study the magnetic properties of ferrimagnetic mixed spins with integer sigma=2 and half-integer S=7/2 in a Blume-Capel model, using Monte Carlo simulations. The considered Hamiltonian includes the first nearest-neighbors and the exchange coupling interactions on the two sub-lattices. The effect of these coupling exchange interactions, in the presence of both the external magnetic field and the crystal field, are studied. The magnetizations and the corresponding susceptibilities are presented and discussed. Finally, we have interpreted the behaviors of the magnetic hysteresis of this model. (C) 2016 Elsevier B.V.
