“…By applying the MC simulation, the magnetic properties of different structures have been studied in our previous work [31][32][33][34][35][36]. As far as our information goes, there exist few studies of the MCE of the triple-layer graphene-like structures by the MC simulation.…”

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.

“…Various studies emphasize the effect of temperature, magnetic field, exchange coupling, and crystal field on the magnetic properties of the system [16][17][18]. Many shaped structures have been studied such as hexagonal core-shell [19][20][21], ladderlike boronene nanoribbon [22], square-octagon lattice [23], Blume-Capel system for square and simple cubic lattices [24][25][26], borophene core-shell structure [27], ladder-like graphene nanoribbon [28][29][30][31], triangular lattice [31,32], diamond-like decorated square [33], rectangle Ising nanoribbon [34].…”

The magnetic properties and phase diagrams of the mixed spin-1/2 and spin-1 Ising model on a honeycomb inside a hexagonal structure have been studied using the Monte Carlo simulations based on the Metropolis update protocol. The effect of different exchange interactions (intralayer and interlayer Js') and single-ion anisotropy D on the magnetic properties, transition and compensation temperatures, and magnetic susceptibility have been investigated. The phase diagrams, T-J and T-D, for different exchange interactions and crystal field values have been examined. Compensation behavior exists for critical values of interlayer's exchange interactions. Our calculations reveal the existence of two points of compensation for a narrow range of negative D. Article highlights A mixed spin Ising model on a centered honeycomb-hexagonal structure was proposed The effects of crystal field and exchange coupling were studied Two points of compensation temperature were exist.

“…This means that increasing the temperature facilitates the entire system's magnetic change from order to disorder, and that the magnetization of the entire system in the paramagnetic phase is totally controlled by h and T. It should be highlighted that comparable variations in hysteresis loops under the impact of temperature have been seen in a number of other investigations, both empirically 60,61 and theoretically. 62,63…”

Monte Carlo simulation was used to study the magnetic properties of the zigzag graphene-like nanoribbon predicated on the ferrimagnetic (5/2,3/2) combined Ising system. The magnetic and thermodynamic properties curves induced by varying exchange coupling interactions and ion anisotropies have all been well studied. For several physical parameters, phase diagrams were provided. Values of exchange couplings and single-ion anisotropy thresholds, indicating whether the system has two compensation temperature points, have been determined. In addition, the impacts of different Hamiltonian parameters on the behavior of multiple-loop hysteresis were explored.
