Critical phenomena in a two-dimensional ferrimagnetic system: Monte Carlo and Mean-Field Analysis

Mixed Spin‐(3/2,7/2) Ising‐Type Ferrimagnet: Monte Carlo–Mean Field Treatment

“…It is evident that compensation temperatures being so dependent on the interplay between the interactions cannot be accurately obtained by standard MF theories that neglect fluctuations by averaging the effect of the interactions. [5,33,87] On the contrary, the results show that the MF technique used can describe adequately the qualitative behavior of the system.…”

“…These models have been effectively used for many years by scientists to analyze interesting magnetic phenomena in magnetically ordered structures that have theoretical interest and practical applications. [1][2][3][4][5][6] The variety of magnetic structures and spins combinations that have been analyzed by these mixed Ising models is quite wide. 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.…”

Exploring thermodynamic characteristics and magnetocaloric effect of an edge-decorated Ising multilayer nanoparticle with graphene-like structure

“…In recent years, Ising model has been applied to many theoretical studies because it can describe rich physical properties [14][15][16]. With the continuous optimization of Ising model, various mixed-spin Ising systems have been extended to elucidate the properties of graphene-like nanostructures by Monte Carlo (MC) simulation [17][18][19][20][21], mean-field theory (MFT) [22][23][24], and effective-field theory (EFT) [25][26][27][28]. B Boughazi et al studied the magnetic properties of graphene-like nanoribbons with mixed spins (5/2, 3/2) using MC method, and reported the size effect on the magnetic susceptibility of the systems [29].…”

Hysteresis and Double‐Spin Compensation Behaviors in a Ferro‐Ferrimagnetic Model of High Half‐Integer Spins

“…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.…”
