The dynamic magnetic properties in a kinetic spin-1/2 bilayer honeycomb lattice (BHL) system with AB stacking geometry under a time-dependent oscillating external magnetic field for both ferromagnetic and antiferromagnetic interactions are studied within the mean-field dynamical equations and the Glauber-type stochastic dynamics approach. First, we study the thermal behavior of the dynamic order parameters. Then, we investigate the temperature dependence of the dynamic total magnetization to ?nd the dynamic compensation points as well as to determine the type of behavior. We also examine the dynamic hysteresis behaviors of the system. Some characteristic phenomena are found depending on the ratio of the physical parameters and frequency of oscillating magnetic field. According to the values of Hamiltonian parameters P-, L-, S-, R-, Q- and N-type compensation behaviors and square-like and S-shaped single hysteresis loops as well as double and triple hysteresis loops exist in the system. Our results are in agreement with some experimental works in recent literature.
