Dynamic magneti̇c features of the mixed spin-1 and spin-5/2ising system on the different lattice structures

In this thesis study, the dynamic magnetic properties of the mixed spin-1 and spin-5/2 Ising system on the bilayer square lattice and bilayer honeycomb lattice with AB stacking geometry are investigated in detail by using the Glauber-type stochastic dynamics based on the mean-field approximation. Firstly, the differential equations which is describing the dynamic behavior of the system are obtained by making use of the Master equation and Glauber transition rates. These equations are solved numerically and the phases existing in the sytem are found by investigating of the average magnetizations as a function of time. Then, the temperature-dependence behaviors of the dynamic magnetizations are studied and the dynamic phase transition temperatures among the existing phases are determined. For both lattice systems, the dynamic phase diagrams are presented on many different planes for various values of the physical parameters in the system. Finally, the effect of the oscillating field frequency on the dynamic phase diagrams is investigated and it is found that the dynamic phase diagrams strongly depends on the frequency.
