Magnetic properties of mixed integer and half-integer spins in a Blume–Capel model: A Monte Carlo study

•Mixed spins with integer and half-integer in a Blume–Capel model is studied.•The effect of coupling exchange interactions is investigated.•The behaviors of the magnetic hysteresis of Blume–Capel model is given.

In this paper, we study the magnetic properties of ferrimagnetic mixed spins with integer σ=2σ=2 and half-integer S=7/2S=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.
