Dynamical hysteresis, a phenomenon observed in ferromagnetic systems near their critical temperature, is investigated within the context of the spin 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.
期刊介绍:
The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public.
Main Categories:
Full-length articles:
Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged.
In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications.
The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications.
The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism.
Review articles:
Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
