Thermodynamic and magnetocaloric properties of a triple-layer graphene-like structure

Thermodynamic and magnetocaloric properties of the triple-layer graphene-like structure with mixed spin-3/2 and spin-5/2 have been reported by applying the Monte Carlo simulation. We found that for such system, various exchange couplings or external magnetic field affect greatly the magnetic behaviors and magnetocaloric effect. For example, the value of magnetization increases and the system becomes more stable with increasing the exchange couplings or external magnetic field. Besides, there exists a peak in each magnetic entropy change curve near the critical temperature. The value of it increases with decreasing exchange couplings or increasing the external magnetic field. In addition, when the exchange couplings decreases or the external magnetic field increases, the relative cooling power enhances. Finally, the hysteresis behaviors have also been investigated in detail.

Automated summary

Thermodynamic and magnetocaloric properties of a triple-layer graphene-like structure with mixed spin-3/2 and spin-5/2 have been studied using Monte Carlo simulation. The results show that various exchange couplings and external magnetic field significantly influence the magnetic behaviors and magnetocaloric effect, leading to enhanced magnetization and system stability with increasing exchange couplings or external magnetic field. Additionally, the presence of peaks in magnetic entropy change curves near the critical temperature, which increase with decreasing exchange couplings or increasing external magnetic field, and the enhancement of relative cooling power as exchange couplings decrease or external magnetic field increases, have been observed.
