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.

Shastry-Sutherland格上的动态滞回

在Shastry-Sutherland晶格的自旋-1/2 Ising模型的背景下，利用平均场理论和Glauber动力学研究了在接近临界温度的铁磁系统中观察到的动态滞后现象。本研究旨在阐明动态迟滞与温度、磁场振幅和反铁磁交换相互作用等参数的关系。结果揭示了复杂的滞后行为，包括对称和非对称回路，取决于哈密顿参数的具体值。值得注意的是，随着温度的升高，系统从铁磁相位转变为顺磁相位，其特征是磁滞环对称性发生明显变化。这些发现与现有的理论和实验研究相吻合，为研究受挫系统的动态磁性提供了新的见解。本文的综合分析有望促进对Shastry-Sutherland磁体及相关材料非平衡磁现象的进一步理论和实验研究。

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.
