Dynamic Magnetic Features of a Mixed‐Spin‐2 and Spin‐5/2 Ising Ferrimagnetic System under a Time‐Dependent Oscillating Magnetic Field: Path Probability Method Approach

“…Masrour and co‐workers [ 16–23 ] and Wang et al [ 24 ] investigated magnetic features of the mixed‐spin (2, 5/2) Ising ferromagnetic system on different lattice structures, such as the Bethe lattice, [ 16,17 ] decorated square and triangular lattices, [ 18 ] a dendrimer structure, [ 19 ] two alternative layers on a honeycomb lattice, [ 20 ] Kekulene structure, [ 21,22 ] a decorated square lattice, [ 23 ] and decorated Kagome‐like lattice [ 24 ] by applying the well‐known methods in equilibrium statistical physics and condensed matter physics. De Le Espriella and co‐workers [ 25,26 ] investigated the magnetic behaviors of the model on a square lattice within the MCS. Moreover, the model utilized a study of thermal and magnetic features of the molecular‐based AFe II Fe III (C 2 O 4 ) 3 nanoribbons [ 27 ] and nanographene layer [ 28 ] within the MCS, the magnetic features of Fe 7 S 8 compound by using by the MFA and MCS, [ 29 ] and the dielectric features of BiFeO 3 /YMnO 3 bilayer films within the MCS, [ 30 ] and Fe 3 S 4 component within Ab‐initio calculations and the MCS.…”

Monte Carlo Simulation of a Mixed Spin‐1/2 and Spin‐3/2 Ising Ferrimagnetic System with Site Dilution

“…Mixed Ising models constitute a useful tool to explore a rich variety of phenomena such as critical behavior, [ 18,19 ] compensation temperatures, [ 20–22 ] hysteresis loops, [ 23,24 ] reentrant behavior, [ 25,26 ] remanent magnetization, [ 27 ] superparamagnetism, [ 28 ] etc. [ 29,30 ] There are many theoretical works that have contributed to the magnetic characterization of various mixed models and lattice structures, such as spin systems (2, 5/2), [ 31,32 ] (3/2, 5/2), [ 33,34 ] (1/2, 5/2), [ 35 ] (2, 3/2), [ 36 ] (1/2, 1), [ 37–39 ] (1, 3/2), [ 40 ] and (1, 2), [ 41 ] to just mention a few. The most common techniques to study these models are mean and effective field theories and numerical simulations based on Monte Carlo techniques.…”

Mixed spin-1 and spin-2 Ising model: study of the ground states

“…Despite their relative simplicity, mixed spin Ising models have proven to be very useful to study the magnetic and critical properties of these materials [6][7][8][9][10]. Mixed Ising models have been studied by mean-field approaches, and numerical simulations [11][12][13][14]. Experimental results of amorphous ferrimagnetic oxides where Fe 3+ ions are present, have been analyzed by mixed Ising models [15].…”

“…An important step for the comprehension of these mixed models is the calculation of their ground state. The ground state diagrams are very useful to understand the low temperature behavior of the system [11,[51][52][53][54][55], and to test the behavior of the techniques used in their simulation. Also, these diagrams can be used to locate regions of the phase parameter where an interesting magnetic behavior can emerge.…”

“…As expected the diagram is symmetric under the change  -The ground state diagram is shown infigure 7. The ground state configurations and their energies are shown in table11. The diagram has four regions separated by four coexistence lines given in table 12.…”
