“…As far as we all know, the increase of T can magnify the disorder of the system and dominates the competition among the exchange interaction and the magnetic field, resulting in the diminution in the area of loops and the appearance of the paramagnetic phase of the system. Similar results are found in some other researches, such as the investigations about the ferroelectric or ferrielectric materials [23,44], BiFeO3/YMnO3 bilayer [39,40], BiFeO3/Co bilayer [41], and some magnetic materials [38,[55][56][57][58].…”

“…From a physical point of view, Q exists under the competition between temperature, exchange interaction and magnetic field, and the larger Jcd is more dominant in the competition among the three. It can bind the spin to a fixed state which is not easy to change, thus leading to the stability and invariability of Q [33][34][35][36][37][38]41]. In Fig.…”

“…In our previous works, much effort was made on the magnetic and dielectric properties of the low-dimensional mixed-spin nano-systems using Monte Carlo simulations [33][34][35][36][37][38]. In addition, such BiFeO3/FM bilayer system was also investigated [39][40][41].…”

Based on the Monte Carlo simulation, a mixed-spin (5/2, 2, 3/2) Ising model is constructed to investigate the dynamic magnetic properties of antiferromagnetic/ferromagnetic YMnO 3 /FM bilayer under the existence of a time-dependent magnetic field. The effects of exchange interaction, oscillating magnetic field as well as temperature are involved in this work. Masses of numerical results of the dynamic order parameter, susceptibility, internal energy, and blocking temperature are obtained with diverse physical parameters. Moreover, the phase diagrams and the hysteresis loops of the system are discussed in detail as well for a better understanding of the dynamic properties of the present system.

The magnetic properties and magnetocaloric effect of an antiferromagnetic/ferromagnetic (AFM/FM) BiFeO3/Co bilayer with mixed-spin (5/2, 3/2) have been studied based on Monte Carlo simulation. The magnetization, susceptibility, and critical temperature are investigated under various exchange couplings and an external magnetic field. In particular, the influence of exchange couplings and an external magnetic field on the magnetic entropy change, adiabatic temperature change, and the relative cooling power (RCP) are studied. The simulation results indicated that the decrease of the exchange coupling and the increase of external magnetic fields can cause an increase of magnetic entropy change, adiabatic temperature change, and RCP. In addition, the hysteresis loops of the system are presented for different exchange couplings and temperatures.

“…In our previous studies, the magnetic behaviors of various nano-systems have been studied by means of MC simulation, such as the zigzag graphene nanoribbon (GRNs) [43], ferrimagnetic mixed-spin Ising nanoisland [44], nanowires [45], nanotubes [46], graphene-like nanoisland bilayer [47], nanoparticles [48] and so on. However, little attention has been applied to the dynamic magnetic properties of Ising graphene-like monolayer under external oscillating magnetic field.…”

Dynamic magnetic properties of the mixed-spin (3/2, 5/2) Ising graphene-like monolayer in an oscillating magnetic field are studied by means of Monte Carlo simulation. The effects of Hamiltonian parameters such as crystal field and time-dependent oscillating magnetic field on the dynamic order parameter, susceptibility and internal energy of the system are well presented and explained. Moreover, much attention has also been dedicated to the phase diagrams with different parameters in order to better comprehend the impacts of these parameters on the critical temperature. Our results reveal that the crystal fields of two sublattices have similar effects on the critical temperature, but the bias field and amplitude of oscillating field have opposite effects on it. We hope that our research can be of guiding significance to the theoretical and experimental studies of graphene-like monolayer.
