| الوصف: | In this work, Monte Carlo simulation was implemented to study the phase diagrams and magnetic properties of a mixed spin (1-1/2-1) three-layer system with a cubic structure. In particular, the effects of the exchange and coupling parameters on the system compensation temperature were explored. More importantly, the effect of the crystal field on the system compensation, critical temperatures, and magnetic and thermodynamic properties of the system have been explored in detail. The crystal field was found to have a profound impact on the system compensation and critical temperatures. Our results suggest that the presence of the crystal field will cause the compensation temperature to exist for a short range of negative crystal field values. Furthermore, the threshold values of the crystal field were found to determine the change in both the compensation and critical temperatures with the variation of the crystal field. The double-peak phenomena confirmed these results in the susceptibility and specific heat curves. Finally, the system magnetic hysteresis loops were studied for different temperatures and crystal field values, revealing the presence of two-step hysteresis loops for several values of these parameters.
