Magnetic Properties and Compensation Temperature Behaviors in the Hexacene-like Nanostructure: A Monte Carlo Study

In this work, we study the ground state phase diagrams and the magnetic properties of the mixed spins (S-1, sigma-7/2) of the Hexacene-like nanostructure. In the first step, the ground state phase diagrams have been established to show the more stable configurations corresponding to different physical parameters. Besides, the Monte Carlo simulations are used to investigate the effects of the temperature, the exchange coupling interactions, the crystal field, and the external magnetic field on the magnetization. Moreover, the hysteresis cycle behaviors have been investigated. It is found that the studied system exhibits two compensation temperatures (T-comp1; T-comp2) which depend on the exchange coupling parameters and the external magnetic field.
