Compensation temperature and hysteresis behaviors of a graphene-like bilayer: Monte Carlo Study

Abstract

Using Monte Carlo method, the compensation temperature and hysteresis loops of a ferrimagnetic mixed spin-3/2 and spin-5/2 Ising-type graphene-like bilayer are investigated induced by different physical parameters such as crystal field, exchange coupling, external magnetic field and temperature. The variation of magnetization, magnetic susceptibility, specific heat and the internal energy with the change of temperature are discussed. In addition, we also plotted the phase diagrams including transition temperature and compensation temperature. Finally, multiple hysteresis loops under the certain parameters are given.

Insight into the magnetic behavior and magnetocaloric effect of a borophene monolayer

“…This indicates that the system becomes the disordered superparamagnetic phase. There have also been some theoretical investigations of borophene nanoribbons with core-shell structure [28], Ising-type polyhedral chain [54] and lowdimensional magnetic nanostructures [55][56][57][58][59][60], as well as experimental observations of bilayer graphene nanoribbons [61] that have revealed similar temperature dependence on the hysteresis behavior.…”

Investigating the magnetic and hysteretic properties of graphyne-based nanostructures: a comparative study of shape effects on critical temperatures, coercivity, and remanence

“…On the other hand, theoretical studies on the magnetic properties of various graphene structures, including nanographene, bilayer or trilayer graphene, and graphyne have been conducted using different calculation techniques such as the mean-field approximation (MFA) [28] and the effective field theory (EFT) [29][30][31][32][33][34][35][36][37], as well as Monte Carlo simulations (MCS) [38][39][40][41][42][43][44][45][46][47][48][49]. In this context, the magnetic properties of graphyne are investigated by the first-principles calculations [18,23,50,51].…”
