Abstract: In this work we consider the dynamic magnetic characteristics induced by a time-dependent magnetic field in the case of a bilayer graphene-like structure. We pay special attention to the influence of the crystal field parameter and exchange interaction parameter on the hysteresis behavior. Among the most interesting magnetic phenomena that have been studied in this work, to understand phase transitions in the system within the framework of the spin-7/2 Ising model and dynamic mean-field theory, include coercivity, remanent magnetization, and the appearance of multiple hysteresis loops. Temperature, exchange interaction parameter, and crystal field parameter can all be used to regulate the system's phase transitions and hysteresis loop types. These parameters will define the magnetic properties of a system that is allowed to take a structure similar to that of bilayer graphene and thereby impact applications related to the development of sophisticated sensors, low energy loss systems, and magnetic storage devices.
