The magnetic and magnetocaloric properties of the nano‐graphene monolayer structure consisting of mixed spins S = 3/2 and σ = 2 are studied by using Monte Carlo simulations. The ground‐state phase diagrams corresponding to several physical parameters are first discussed. The influence of the number of lattice sites on the total and partial magnetizations and the magnetic susceptibilities has been investigated. The critical temperature is deduced. The effect of exchange interaction, external magnetic, and crystal field on total magnetizations is studied. Magnetic hysteresis cycles are obtained. Specific heat change and magnetic entropy changes are inferred for several magnetic fields. Finally, the relative cooling power is determined.

“…Bobák et al by employing this method to investigate the phase diagrams of honeycomb lattice, the square and simple cubic lattices with mixed spins and obtained tricritical points and compensation point [28][29][30]. Masrour et al carried out the Monte Carlo (MC) simulation to investigate magnetic behaviors of various nanostructures such as decorated square lattice, nano-borophene, and bilayer Kekulene with mixed spin (2, 5/2) [31][32][33]. Additionally, the related structures of multi-layer graphyne have also captured the attention of scientists.…”

“…Beyond this, a major breakthrough has been made in the research of carbon-based functional materials, and a sandwich-like carbon sheet, has been successfully synthesized, as an enhanced cathode for lithium-ion batteries. Moreover, the mixed spin (2, 5/2) Ising system has gained significant attention in recent years due to its ability to explain experimental findings in molecular-based magnets [45,46] and serve as an appropriate model for diverse low-dimensional magnetic systems [27,31,32,41]. These inspires us to investigate physical properties of a graphyne-like sandwich structure.…”

By employing effective-field theory with correlations, the effects of exchange couplings and anisotropies on the physical properties of graphyne-like sandwich structure with a mixed-spin (5/2, 2) were analyzed. The various characteristic curves of the hysteresis loops, magnetization, susceptibility, internal energy, specific heat, as well as phase diagram was obtained. We found the multiple-loop hysteresis behaviors and reentrant phenomenon under certain conditions. Moreover, we also depicted the variation curves of dynamic magnetization under the impact of a periodically oscillating magnetic field. It is shown that a time-dependent and independent magnetic field can control and induce the disorder and order of the system.

“…36 In some of our previous works, we have used Monte Carlo simulations to investigate further the irresistibility of many structures. [37][38][39][40][41][42] On the other hand, FADIL et al 43 have established the emergence of multiple hysteresis cycles and polarization plateaus by using the Monte Carlo investigation for a fullerene-like system. Also, the magnetizations of plateaus for a double Fullerene Core/ Shell Like-Nanostructure have been examined in an External Magnetic Field by applying the Monte Carlo Study.…”

We explored the magnetic and magnetocaloric properties of the C56 Fullerene-like system formed by the mixed spins 2 and 3/2. We applied Monte Carlo simulations using the Metropolis algorithm and show the effects of different physical parameters. We also established the ground state phase diagrams, at zero reduced temperature, in different planes formed by the reduced external magnetic field, the reduced coupling interaction between the mixed spins, and the reduced crystal field. We found that the total magnetizations predict a specific reduced critical temperature value, confirmed by the peaks observed in the magnetic susceptibilities. To elucidate the behavior of the magnetic entropy changes -ΔSm, of the C56 system, for several external magnetic field values we show that the reduced critical temperature value tC increases when increasing the reduced external magnetic field. In addition, we show the dependency of the maximum “magnetic entropy change” as a function of the reduced external magnetic field. We found an almost linear increase for this parameter when increasing the reduced external magnetic field values. The obtained hysteresis cycles of the studied system showed a decreasing effect of the reduced crystal field followed by a decrease of the magnetic hysteresis surface cycles, as well as the corresponding reduced coercive magnetic field values.
