Abstract

The dynamic compensation and dynamic hysteresis features of the mixed bilayer Ising system (MBIS) consist of spin-1 and spin-1/2 on a bilayer square lattice and have been studied extensively with the use of the effective-field theory and Glauber type stochastic dynamic. Firstly, the thermal variations of the total magnetization were investigated in order to find the compensation types of the MBIS. The six compensation types were found to be the Q-, R-, P-, N-, S-, and L-types. Then, the effects of the temperature, interlayer coupling constant, crystal field, and oscillating field frequency on the dynamic magnetic hysteresis properties were widely studied.
