Abstract: | This paper outlines the magnetic properties of a tri-layers nano-dicoronylene like-structure, using Monte Carlo simulations under the Metropolis algorithm in the Blume Capel model. The top and bottom layers are composed by S-spins (S = 0, ±1), While the middle layer is composed by σ-spins (σ=±3/2, ±1/2). Each layer contains 48 atoms. We establish, in six various planes, the ground state phase diagrams. Still, we present the thermal variation of partials and total magnetization and susceptibility for several values of exchange coupling interactions and crystal field. Also, the hysteresis cycles have been reported for selected values of temperature and exchange coupling interaction. The compensation and blocking temperatures values increases when increasing the exchange coupling parameter in the extreme layers. |
