Abstract: The dynamic magnetic characteristics and hysteresis behaviors of the double-layered fullerene-like X540@Y540 structure are explored by using the Monte Carlo method. By introducing the non-magnetic layers, the influence of interlayer interaction JRKKY is studied. In the presence of the non-magnetic layer and dynamic magnetic field, the system displays a multitude of magnetic behaviors, and the compensation temperature Tcomp emerges. To further examine the influence of physical parameters on the phase transition temperature TC and compensation temperature Tcomp, we present the curves and 2D color maps of the phase diagrams. Finally, we also investigate the dynamic hysteresis behavior. Due to the existence of relaxation behavior in magnetic systems, when physical parameters change, the position, area, and shape of the dynamic hysteresis loop all change, which is also the unique magnetic behavior exhibited by magnetic systems in dynamic magnetic fields.
