“…Therefore, the stronger the magnetic field applied, the larger the magnetic moment and the lower the energy, which is consistent with the phenomenon shown by many low-dimensional magnetic materials. 59–63 However, with a further increase in temperature (from 400 K to 600 K), the value of the magnetic moment curve applying a strong magnetic field (4 T or 5 T) is no longer maximum. This is because high temperature will drive the system to transform from order to disorder, while a strong magnetic field will force the system to become more orderly.…”

“…MC computational techniques have proven to be efficient for the analysis of Ising-type magnetic models. [54][55][56] To simulate the system defined by the Hamiltonian in Equation 1, we apply a thermal bath-type algorithm where states are generated at random. Spins are randomly selected through the lattice, and are changed according to the Boltzmann probability.…”

Mean field and Monte Carlo simulations techniques are applied to study the behavior of a mixed Ising spin model in a square lattice where spins 7/2 are located in alternating sites with spins 3/2. There is an antiferromagnetic interaction between nearest neighbors, ferromagnetic interactions between next-nearest neighbors, crystal fields, and a magnetic external field. The role of the different interactions in the magnetic behavior of the system is explored. It is found that depending on the combination of parameters in the Hamiltonian this system presents multiple hysteresis loops, exchange bias, compensation temperatures, and discontinuous magnetizations. The results are compared with previous studies that do not include the ferromagnetic next-nearest neighbor interactions and found that they can have a strong effect in the magnetic behavior of the system.

“…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.…”

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.
