摘要

This study investigates the magnetic characteristics of a mixed-spin model (σ = 2 and S = 3/2) residing on a specific geometric framework known as the square-hexagon-octagon. Leveraging Monte Carlo simulations, we scrutinize RKKY-type interactions, meticulously examining the ramifications of lattice vibrations, as well as exchanging coupling parameters contingent on time and temperature. Our investigations unearth magnetic phase transitions, encompassing magnetic spin reorientation and transitions from ferrimagnetic to paramagnetic states. Moreover, we dissect hysteresis loops, delineating their susceptibilities to non-magnetic layer thickness, exchange interactions, temperatures, and crystalline fields. These findings markedly enhance our comprehension of magnetic phenomena within intricate structural configurations.
