Abstract
- Using the mean field approximation (MFA), we have successfully investigated the magnetic properties of the mixed spin S j = ± 3 , ± 2 , ± 1 , 0 and σ i = ± 3 2 , ± 1 2 Ising ferrimagnetic system in a graphene layer. The effects of different physical parameters, namely exchange interactions, anisotropies, external field and temperature on the critical, first-order, compensation and hysteresis behaviors have been examined. The results show that, for specific values of these parameters, interesting phenomena appeared, such as compensation and multi-loop hysteresis behavior. It was shown that the compensation phenomenon only occurs if the exchange interaction J A (interaction between spins σ i), is greater than a certain minimum value J A m i n. We have also shown that, for fixed values of the anisotropies, the relation between J A m i n and the exchange interaction J B (interaction between S j), is a linear one. In addition, we found that each of the behaviors mentioned above is sensitive to the change of a certain physical parameter. Finally, we have verified that our results are comparable with those of other works. • The effects of physical parameters on magnetic properties were examined. • The system presents a first- and second-order transition. • Compensation appears in the system for specific values of physical parameters. • The phenomenon of multi-loop hysteresis cycles is present in the system.
