“…Therefore, two compensation points exist in a narrow range of D (i.e., − 0.7 to − 0.6). These results agree with the work done by A. Boubekri on ferrimagnetic mixed spin Ising trilayer nano-graphene structure [39]. This is important in the thermomagnetic recording, where small temperature changes reverse the magnetization [45].…”

“…We will use the MC method in this study. A similar system to this structure can be found in the nano-graphene system [39] and be applicable for bimetallic layered compounds [40,41]. Similar works were done by us using different crystal structures [18,42,43].…”

“…5b, we show the magnetization 3, 4, and 5, except for the existence of two compensation points in a narrow range of the crystal anisotropy of negative values. In fact, and according to previous studies in different layer structures effective field method was used and found that the effect of D influences the location of compensation temperature, but in our work, we include intralayer coupling J 1 and J 2 which is not included in the previous work [38,39].…”

“…Therefore, the mixed spin lattices such as this honeycomb-hexagonal adopted here reveal two compensation points. It has been argued that such two compensation points exist when nearest neighbor interactions of spin 1/2 layer are considered [37,39,46]. Such finding is essential in the thermomagnetic recording where a slight temperature change reveres the magnetization [45].…”

“…Therefore, at least two relevant interactions of different natures must exist for compensation. These interactions will be shown when one constructs the Hamiltonian of the system under study [38,39].…”

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.

Herein, thermomagnetic properties of a ferro‐ferrimagnetic system with magnetic moments of values , and alternating on a square lattice, are investigated. These properties are framed in hysteresis, double‐spin compensation, and discontinuous behavior of the system. Through Monte Carlo simulations, the temperature dependence of the magnetization and magnetic susceptibility of the system for zero and nonzero values of an applied external magnetic field are analyzed. The hysteresis behavior of the model for different temperature values is also studied. It is found that the system experiences double‐spin compensation and multiple hysteresis loops when it is subjected to different values of single‐ion anisotropy and magnetic fields. The increase in the strength of the magnetic field generates discontinuities in the magnetization, and the inversion of its polarity destroys the compensation points. Finally, a phase diagram is presented with the critical, spin compensation, and discontinuous temperatures in terms of the magnetic and anisotropic fields for the ferri‐ and ferromagnetic cases. The results are compared with a recent investigation of this system that does not include the antiferromagnetic next‐nearest‐neighbor interactions, which influences the magnetic behavior of the model.
