摘要：
In this work, we studied the magnetic properties and hysteresis loops of a mixed spin-1/2 and spin-3/2 bilayer system using the mean-field approximation based on the Bogoliubov free-energy inequality. The two layers are separated by a number of non-magnetic layers with a graphene structure. First, we plotted a ground-state phase diagram at zero temperature. Then, we explored the thermal behavior of total magnetization under the effect of the indirect exchange interaction JR between the two layers, and we deduced the phase diagram for T not equal 0 . We also examined the influence of non-magnetic layers on magnetic hysteresis behavior for different temperatures.
