论文摘要
晶体对称性，磁性，带拓扑和电子相关性的相互作用可以是凝分物质中量子相变的起源。特别是，方形材料一直是一个多功能平台，用于研究该相互作用产生的丰富现象。在这项工作中，我们报告了基于方形晶格的磁性拓扑半学GDSB_ {x} te_ {2-x-δ}的详细磁研究。我们报告了沿三个晶体学取向的H-T磁相图，并表明，对于已知电荷密度波失真存在的材料，可以确定许多不同的磁相。此外，数据还提供了存在抗磁磁性阶段的线索，从理论上预测但尚未在散装材料中进行实验证实。
The interplay of crystal symmetry, magnetism, band topology and electronic correlation can be the origin of quantum phase transitions in condensed matter. Particularly, square-lattice materials have been serving as a versatile platform to study the rich phenomena resulting from that interplay. In this work, we report a detailed magnetic study on the square-lattice based magnetic topological semimetals GdSb_{x}Te_{2-x-δ}. We report the H-T magnetic phase diagrams along three crystallographic orientations and show that, for those materials where a charge density wave distortion is known to exist, many different magnetic phases are identified. In addition, the data provides a clue to the existence of an antiferromagnetic skyrmion phase, which has been theoretically predicted but not experimentally confirmed in a bulk material yet.
