Özet

Dynamical hysteresis, a phenomenon observed in ferromagnetic systems near their critical temperature, is investigated within the context of the spin -1/2 Ising model on the Shastry-Sutherland lattice using mean-field theory and Glauber dynamics. This study aims to elucidate the dependence of dynamic hysteresis on various parameters such as temperature, magnetic field amplitude, and antiferromagnetic exchange interactions. The results reveal complex hysteresis behaviours, including both symmetric and asymmetric loops, contingent upon the specific values of the Hamiltonian parameters. Notably, as the temperature increases, the system transitions from a ferromagnetic to a paramagnetic phase, characterized by distinct changes in hysteresis loop symmetry. These findings align well with existing theoretical and experimental studies, offering insights into the dynamic magnetic properties of frustrated systems. The comprehensive analysis presented here is expected to stimulate further theoretical and experimental research on nonequilibrium magnetic phenomena in Shastry-Sutherland magnets and related materials.
