“…[15] The dynamical behavior of these mixed Ising structures in the presence of oscillating magnetic fields has been the object of many recent studies, particularly the dynamical hysteresis loops [16][17][18] and the dynamical compensation temperatures. [19][20][21] Combinations of half-integer Ising models have been useful to characterize and model some crystal lattices. For example, properties such as internal energy, specific heat, and blocking temperatures of nanographene bilayers have been modeled by the 3/2-5/2 spin combination; [22,23] multicompensation phenomena have been found in many mixed systems.…”

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.

“…Research on thermomagnetic properties of various types of materials has increased over the years both experimentally [1][2][3][4] and theoretically, [5][6][7][8] with the purpose of strengthening new technologies that will be of help for the welfare of humanity. Although physical phenomena such as interesting multi-cycle hysteresis behaviors, [9][10][11][12] compensation points in equilibrium [13][14][15] and out of equilibrium, [16,17] and second-order and firstorder phase transitions, [18][19][20] as well as the tricritical point phenomena [21][22][23] and magnetic coercive fields and remanent magnetization [24,25] have been characterized as contributors to scientific development, today many molecular magnetic systems configured in various structures continue to be investigated.…”

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.

“…Since the magnetic properties of layered composite materials may differ from their corresponding bulk systems, they have received considerable attention. The mixed and pure layered Ising systems with antiferromagnetic exchange interaction provide simple but interesting models for studying layered composite materials [2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

Using the path probability and lowest approximation of cluster variation method, we study the dynamic and equilibrium properties of a bilayer magnetic system, consisting of two ferromagnetic monolayers antiferromagnetically coupled for different spins (σ = 1/2 and S = 1). Firstly, numerical results of the monolayer and total magnetizations are presented under the effect of the diverse physical parameters, and the phase diagrams of bilayer system are discussed. Then, since it is well established that the path probability method is an effective method for the existence of metastable states, the time evolution of monolayer- and total magnetizations is investigated.
