Study of magnetic properties of the fullerene C36 structure by Monte Carlo simulations

In this work, we used Monte Carlo simulations to illustrate the magnetic properties of the structure of fullerene C-36 formed with the mixed spins 3/2 and 1. We applied the reduced crystal field, the reduced external magnetic field, and the different reduced coupling interactions between the mixed spins of the studied system. In the absence of any temperature fluctuations, the ground-state phase diagrams have been established and discussed in different planes formed with the external magnetic field, the coupling interactions between spins and the reduced crystal field. In addition, the impact of rising reduced temperature on the magnetizations and the derivative of magnetization has been shown. It is found that, at specific reduced temperature values, the system could change from the ferromagnetic to the paramagnetic phase. Also, the variation of the reduced exchange coupling interactions leads to increasing values of the magnetic reduced coercive field, shown by the hysteresis loops.
