Anisotropic exchange interactions in Co<sub>3</sub>Sn<sub>2</sub>S<sub>2 </sub>Kagome lattice ferromagnets

ORAL

Abstract



The study explores the magnetic interactions of the Kagome lattice ferromagnet Co3Sn2S2, which exhibits exotic topological states in condensed matter physics. The material hosts a giant anomalous Hall state and the antiferromagnetic state in the a-b plane competes with the ferromagnetic order. As the temperature approaches Tc, the antiferromagnetic state gains strength, leading to strange magnetization dynamics. The study reveals that anisotropic exchange interactions are the underlying mechanism, causing long-range magnetism to form and grow with increasing temperature.
