【 摘 要 】

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 semimetal GdSbxTe2-x-delta. 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 hints towards the existence of an antiferromagnetic skyrmion phase, which has been theoretically predicted but not experimentally confirmed in a bulk material yet.
