Magnetism of a Magnetic-ion-intercalated Transition Metal Dichalcogenide with a Chiral Structure

ORAL

Abstract

Chiral magnets are materials where various intriguing spin orders including skyrmions, chiral soliton lattice, and topological domain walls can be found in the presence of the structural chirality. On the other hand, the hunting for exotic magnetic systems that are possible to fabricate functional two-dimensional devices for applications is also in high demand. In this work, we demonstrate that a magnetic-ion-intercalated transition metal dichalcogenide (TMD) is a layered chiral magnet according to our magnetic measurements and Lorenz transmission electron microscopy studies. Using transmission electron microscopy and magnetic force microscopy, we investigated its chiral structural domains and magnetic domains, respectively. Their domain topologies and relations will also be discussed.
