Magneto-transport and magnetic ordering in the intercalated transition metal dichalcogenides.

Noncentrosymmetric magnetic systems have been found to host a variety of exotic, and in some cases topologically protected, magnetic states such as skyrmion lattices, bimerons, chiral solitons and helimagnetism to list a few examples. One such class of material that has faced increased scrutiny in recent years for their magnetism are two-dimensional (2D) materials. The intercalated transition metal dichalcogenides (TMDCs) are an interesting class of materials exhibiting ferromagnetic or antiferromagnetic ordering. Cr_1/3NbS₂ is an example of a 2D TMDC where the structure consists predominately of layers of Nb and S where the Cr atoms have been intercalated between the layers. Cr_1/3NbS₂ exhibits chiral helimagnetic ordering as well as a chiral soliton lattice. We present our recent studies of the magneto-transport properties and magnetic state in these TMDCs where several different magnetic atoms (Cr, Mn, V) have been intercalated.
