▎ 摘  要

In this paper, we study the magnetic properties of a tri-decorated (sigma = 1/2, S = 1, q = 3/2) graphene structure using Monte Carlo simulations (MCS). Indeed, we first elaborate the ground state phase diagrams and then, we found that from 2x3x4 = 24 phases, the only stable configurations are: (sigma, S, q) = (-1/2, +1, -3/2), (+1/2, -1, +3/2), (-1/2, -1, -3/2), (+1/2, +1, +3/2), (-1/2, -1, +3/2), (+1/2, +1, -3/2), (-1/2, +1, +3/2), (+1/2, -1, -3/2), (+1/2,0, +3/2), (-1/2, 0, -3/2), (+1/2,0, +1/2) and (-1/2, 0, -1/2). For low reduced temperature values, the partial magnetizations are found to be in good agreement with the corresponding ground state phase diagrams. The corresponding partial susceptibilities show a notable peak around the reduced temperature value 2.0 in the absence of the external magnetic field (h/J(sigma S) = 0.0) and crystal field (Delta/J(sigma S) = 0.0). To complete this study, we present and discuss the magnetic hysteresis loops.
