“…They are found double compensation points and observed multi-loop hysteresis behaviors in under different parameters. Wang et al [58] have examined the physical properties of the bilayer graphyne with a mixed spins (5/2, 2) described by using EFT with correlations. They are obtained multiple compensation temperatures.…”

“…In this context, the magnetic properties of graphyne are investigated by the first-principles calculations [18,23,50,51]. The magnetic properties of the graphyne-based nanostructures based on MCS [52][53][54][55][56][57] and EFT [58,59] have been also studied. Drissi and Zriouel [52] have studied magnetic properties and hysteresis behaviors of graphyne core/shell nanoparticles using MCS.…”

Our study aims to investigate the physical properties of graphyne-based nanostructures, with a particular focus on their magnetic and hysteretic features. We analyze the influence of shape on these properties in an Ising-type graphyne structure using the effective field theory (EFT) method. Our research focuses on the critical and compensation temperatures, coercivity, and remanence of the graphyne structure in different shapes, ranging from alpha (α) to beta (β) to gamma (γ). We use the magnetization curves and hysteresis loops obtained from central and intermediate spins. We also illustrate the behavior of the coercive field and remanent magnetization as well as hysteresis loop the effect of exchange interactions r and s as well as temperature. We observe N- and R- type compensation in the β graphyne, and L- and S- type compensations in the γ graphyne. We also find that the widest hysteresis is observed in γ graphyne.

“…In addition, MC simulations allow the study of the magnetic behaviors and magnetocaloric effects of nano-systems [27][28][29][30]. In our previous study, we successfully described the magnetic and thermodynamic properties of a nanosystem using the Ising model [31][32][33]. Moreover, dynamic phase transitions and hysteresis loop behaviors have raised significant interest [34,35].…”

Based on the Monte Carlo method, we examined the dynamic magnetic behaviors and magnetocaloric effect of a Kagome lattice subjected to the influence of time-dependent oscillating and time-independent magnetic fields. We used the Ising model to describe the Kagome lattice and study the dynamic order parameters, blocking temperature, internal energy, and phase diagrams. The results revealed that exchange coupling increases the stability of the system and the bias field induces order; however, the time-dependent oscillating magnetic field induces disorder. In addition, the magnetocaloric properties, changes in magnetic entropy, and relative cooling power of the Kagome lattice were investigated.

“…Besides, trilayer graphyne with different arrangement styles (AAA, ABA, and ABC) are all stable, however, ABA-stacking styles is the most stable. In our previous studies, we also successfully used EFT and MC simulation to research the magnetic behaviors of various nanostructure, such as, Lieb-like lattice [38], hexagonal decorated nanoparticle [39], bilayer graphene-like [40], and graphyne-like [41]. Furthermore, we have also examined the magnetization and susceptibilities of graphene-like sandwich structure with mixed spins by using EFT [42].…”

“…Beyond this, a major breakthrough has been made in the research of carbon-based functional materials, and a sandwich-like carbon sheet, has been successfully synthesized, as an enhanced cathode for lithium-ion batteries. Moreover, the mixed spin (2, 5/2) Ising system has gained significant attention in recent years due to its ability to explain experimental findings in molecular-based magnets [45,46] and serve as an appropriate model for diverse low-dimensional magnetic systems [27,31,32,41]. These inspires us to investigate physical properties of a graphyne-like sandwich structure.…”

By employing effective-field theory with correlations, the effects of exchange couplings and anisotropies on the physical properties of graphyne-like sandwich structure with a mixed-spin (5/2, 2) were analyzed. The various characteristic curves of the hysteresis loops, magnetization, susceptibility, internal energy, specific heat, as well as phase diagram was obtained. We found the multiple-loop hysteresis behaviors and reentrant phenomenon under certain conditions. Moreover, we also depicted the variation curves of dynamic magnetization under the impact of a periodically oscillating magnetic field. It is shown that a time-dependent and independent magnetic field can control and induce the disorder and order of the system.
