Study of the Blume-Emery-Griffiths Model for Mixed Carbon-Like Nanotube: Monte Carlo Study

Article scientifique 2022 Anglais

Résumé

Abstract Monte Carlo study under the Metropolis algorithm is performed to investigate the ground phase diagrams and hysteresis electric cycles by using the Blume-Emery-Griffiths (BEG) model with the mixed spins (S-1, σ-3/2). Firstly, the ground state phase diagram has been established to show the more stable configurations corresponding to physical parameter EZ/JC. Moreover, the hysteresis electric cycle behaviors have been investigated by varying temperature, exchange coupling interactions, crystal field and biquadratic parameter of the carbon-like nanotube. It is found that the increase of the crystal field and the biquadratic exchange parameters decreases the surface of the loops leading to the apparition of the polarization plateaus.
