Reentrant phenomena of a mixed spin (5/2,3/2) Isotropic Blume–Emery–Griffiths model (BEG) on a graphene layer.

Magnetic properties of a mixed spins (5/2,3/2) Isotropic Blume–Emery–Griffiths model (BEG) on a graphene layer have been studied within the framework of the Monte Carlo simulation. We have investigated the effects of the next nearest neighbors exchange interaction, the biquadratic exchange interaction and the longitudinal magnetic field on the critical and magnetic behaviors of the system. Interesting phenomena have been remarked. In particular, for appropriate parameters of the Hamiltonian, the system exhibits magnetization plateaus, double reentrant phenomena and compensation behavior. • Magnetic properties of a mixed spins - (5/2,3/2) Isotrope BEG model on a graphene layer have been studied by using MCS. • The system shows double reentrant phenomena. • The compensation biquadratic exchange coupling and the compensation temperature can emerge in the system.
