“…On the contrary, a relatively large ω means that a short period applies to the present system, weakening the influence of the oscillating magnetic field on the system and making the system keep order longer, so the TB becomes higher. The similar phenomenon is also shown in the study about nano-graphene bilayer [28], two-dimensional square lattice [32], and double-layer cor-shell graphene nanoisland [52]. Next, turn our attention to 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.

“…Some examples are as follows: nanostructures such as nanographene layers alternated with spins 1/2, 3/2, and 5/2 that have compensation points in the presence of an external magnetic field, [ 7,8 ] cluster dendrimers (CD) of core/shell (CDCS) with the (3/2‐2) spin mixture, and a mixed spin‐(2‐3/2) Heisenberg single‐walled nanotube superlattice, [ 9,10 ] Ising nanoribbons, [ 11 ] Ising nanocubes, [ 12 ] Ising nanowires, [ 13,14 ] and nanoislands. [ 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 [ 16–18 ] and the dynamical compensation temperatures. [ 19–21 ] Combinations of half‐integer Ising models have been useful to characterize and model some crystal lattices.…”

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.

“…In addition, we found that the system exhibits rather simple DPDs compared with the Hamiltonian of the system that contains bilinear, biquadratic, and crystal‐field interactions on a square lattice. [ 39,40,44,45 ] Recently, Wu et al [ 50 ] reported more simple DPDs that were obtained in investigating the dynamic magnetic features of a double‐layer core–shell graphene structure. They stated that the simple DPDs may be due to the bias magnetic field that plays in the dominant role in the DPT.…”

“…For examples, various dynamic properties of the model, such as DPTs, DPDs, dynamic hysteresis, and compensations behaviors of the model on a square lattice, [ 43–46 ] bilayer square lattice, [ 47 ] a layered honeycomb lattice, [ 48 ] a hexagonal lattice, [ 49 ] and different lattice structures, have been investigated within the DMFA [ 37,40–43 ] and the path probability method (PPM). [ 45,46 ] Wu et al [ 50 ] studied the mixed‐spin (2, 5/2) IFS in a time‐dependent magnetic field to investigate the dynamic magnetic features of a double‐layer core–shell graphene nanoisland within the dynamic MCS.

“…Finally, these explanations and ref. [1‐50] indicate that in the past few decades, intensive theoretical works have been performed to understand the magnetic properties of the mixed‐spin‐2 and spin‐5/2 IFS as well as ferrimagnetic materials and molecular‐based magnets. This system provides good models to investigate ferrimagnetic materials and molecular‐based magnets that are currently the subject of a great deal of interest due to their possible useful properties for technological applications as well as academic research.…”

A study, within the path probability method, of the dynamic magnetic features of the mixed spin (2, 5/2) Ising ferrimagnetic system on a hexagonal lattice under the presence of a sinusoidal external magnetic field is presented. The Hamiltonian of the system contains intersublattice, intrasublattice, and crystal‐field interactions. The intersublattice interaction is taken as antiferromagnetic. The time variations of average dynamic magnetizations and the thermal behavior of the dynamic magnetizations are investigated to obtain the phases in the system and to characterize the nature of the dynamic phase transitions and find the dynamic phase transition temperature points. The dynamic phase diagrams in six different phase planes are presented, in which they contain the paramagnetic (p) phase, three different ferrimagnetic (i 1, i 2, i 3) fundamentals, and the p + i 1, i 1 + i 2, and i 2 + i 3 mixed phases as well as the dynamic tricritical point and the dynamic double critical end point, depending on the interaction parameters. The dynamic compensation behavior is also examined and only N‐type behaviors are observed. Some of the obtained dynamic phase diagrams are in qualitatively good agreement within some works on the dynamics of mixed‐spin Ising system.
