Abstract
We have studied the magnetic properties of the mixed spin σ=±32,±12 and spin S=±52,±32,±12 Ising ferrimagnetic system in a graphene layer by means of Monte Carlo simulations. The effects of next-nearest neighbors exchange interactions and crystal field anisotropy on the critical and compensation behavior of the system have been investigated. The results show that, for a system with given values of the crystal field anisotropy and exchange interaction constants, a compensation point only exists if the values of the spins in the ground state are such that |S|>|σ| and Jσ is higher than a certain value Jσmin. It was shown that the relationship between Jσmin and JS is linear for a given value of the crystal field constant. The compensation and the critical temperature are very sensitive to the change of JS and Jσ, respectively, while the crystal field anisotropy affects both temperatures to a large extent.
