“…We should mention that the compensation behaviors have been experimentally obtained in reference [60] and theoretically in different Ising systems [28,[61][62][63][64][65][66][67][68]. It is also worth mentioning that recently, the compensation behaviors have been theoretically obtained in the kinetic Ising systems [69][70][71].…”

The dynamic magnetic properties in a kinetic spin-1/2 bilayer honeycomb lattice (BHL) system with AB stacking geometry under a time-dependent oscillating external magnetic field for both ferromagnetic and antiferromagnetic interactions are studied within the meanfield dynamical equations and the Glauber-type stochastic dynamics approach. First, we study the thermal behavior of the dynamic order parameters. Then, we investigate the temperature dependence of the dynamic total magnetization to ?nd the dynamic compensation points as well as to determine the type of behavior. We also examine the dynamic hysteresis behaviors of the system. Some characteristic phenomena are found depending on the ratio of the physical parameters and frequency of oscillating magnetic field. According to the values of Hamiltonian parameters P-, L-, S-, R-, Q-and N-type compensation behaviors and square-like and S-shaped single hysteresis loops as well as double and triple hysteresis loops exist in the system. Our results are in agreement with some experimental works in recent literature.

“…For example, in Refs. [56,57], thermal variations of time-averaged magnetizations, dynamic correlations between time-dependent magnetic fields and magnetization, and hysteresis loop areas of cylindrical Ising nanowire and nanotube systems have been elucidated by benefiting from Glaubertype stochastic processes [59]. It is underlined that, depending on the Hamiltonian parameters, the considered systems represent different types of magnetization profiles according to the Nèel theory of ferrimagnetism [60,61].…”

Abstract:We implement Monte Carlo simulations to determine dynamic phase transition features of both cubical and spherical nanoparticles composed of spin-1/2 cores surrounded by a spin-1 shell layer. The particles are subjected to an oscillating magnetic field. We plan these particles such that they have similar volumes. It is observed that the nonequilibrium magnetic phase transition temperatures of the particles with similar volumes explicitly depend on their geometrical shapes as well as the system parameters. The cubic one has a higher transition temperature than the spherical one for the small interface coupling, whereas the transition temperature of the spherical particle becomes higher than that of the cubic one with further increment in antiferromagnetic coupling. We also analyze the magnetic features of the particles, such as dynamic remanence and coercivity treatments. Our simulation results suggest that the spherical particle has almost the same coercivity behavior as the cubic one for some considered system parameters. However, there are some differences in the context of remanence behaviors between spherical and cubic core-shell nanoparticles.

“…However, as far as we know, the DPT temperatures of the magnetic nanostructured materials have only been investigated a few works by usin EFT [55][56][57][58] and MCs [59][60]. Therefore, the aim of this paper is to investigate temperature dependence of the dynamic magnetizations and the dynamic phase diagrams, including compensation points, of the HIN in an oscillating magnetic field within the DEFT.…”
