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.

“…Graphone nanoribbons (GONR) are a class of graphene allotropes that exhibit magnetism [6]. Using Monte Carlo (MC) calculations and mean field theory (MFT), it was shown that the critical temperature T c reduces as a step function versus the ribbon widths in pure GONR [7] and T c increases with the number of substituted transition metal (TM) impurities in doped GONR [8]. On the other hand, the eect of 3d TM (V, Cr, Mn, Fe and Co) nanowires on the magnetic properties of doped graphyne were reported [9,10].…”

Magnetic properties and hysteresis behaviors of a graphyne core/shell nanoparticles are studied within the framework of Monte carlo calculations. We analyze in detail the ground-state phase diagrams in different planes. We examine the effects of the extrinsic and intrinsic parameters of the Hamiltonian on the magnetic and thermodynamic quantities of the system, namely, the total magnetization, its corresponding susceptibility, the hysteresis curves, and the compensation behavior that is of crucial importance for technological applications such as thermo-optical recording. A number of characteristic behaviors are found, such as the occurrence of one and two compensation temperatures and the existence of two new and non-classified types of compensation behavior in addition to the Q-, P- and N-types. Moreover, single and triple hysteresis loops, which exhibit different step effects and various shapes, are observed.
