Critical and compensation behaviors of a graphyne bilayer: A Monte Carlo study

Abstract Applying Monte Carlo simulation, the critical and compensation behaviors of a graphyne bilayer are explored in this study. The effects of the crystal field and exchange coupling on the magnetic behaviors and the phase diagrams are presented in detail. The results show that the critical temperature increases as the crystal field decreases or the exchange coupling increases. In addition, the double compensation points can also be found in this system. Furthermore, we give the hysteresis loops under different parameters, and the multi-loop hysteresis behaviors are observed.
