Abstract: Influences of crystal-fields (DA and DB) and interlayer coupling interactions (J3) on dynamic magnetic critical behaviors of a mixed-spin (3/2, 2) bilayer system under an oscillating magnetic field are investigated by the Glauber-type stochastic dynamics based on the mean-field theory. For this purpose, dynamic phase diagrams are constructed in the reduced temperature and magnetic field amplitude plane for the ferromagnetic/ferromagnetic (FM/FM), antiferromagnetic/ferromagnetic (AFM/FM) and AFM/AFM interactions in detail. We observe that the influences of DA, DB and J3 interactions parameters on the behavior of the dynamic phase diagrams are very much.
