New Gd-based magnetic compoundGdPt2Bwith a chiral crystal structure

Chirality, a fundamental property of symmetry, can produce unique magnetic and electronic properties in materials. The discovery of new magnetic compounds with ``chirality'' leads to the exploration of exotic physical phenomena in chiral crystals. Here, the authors report the discovery and single-crystal growth of a novel Gd-based magnetic compound GdPt${}_{2}$B with a chiral crystal structure. GdPt${}_{2}$B exhibits a magnetic transition at 87 K and shows magnetic properties arising from the competition between ferromagnetic and Dzyaloshinskii-Moriya interactions. These results pave the way for demonstrating novel spin textures, topological electronic states, and exotic transport phenomena in the novel rare-earth-based chiral crystal.
