Controlling and Tuning the Magnetic Ground State in an Intercalated Transition Metal Dichalcogenide

ORAL

Abstract

It is possible to engineer magnetism in layered TMDs XS2 (X=transition metal) via intercalation of magnetic transition metals. In particular, iron intercalation (1/3 Fe per X site) introduces a two-dimensional magnetic sublattice between XS2 layers. Despite adopting identical crystal structures with near-identical lattice parameters, the magnetic ground states of Fe1/3NbS2 and Fe1/3TaS2 are antiferromagnetic and ferromagnetic, respectively. Due to their chemical similarity, these two materials can form end members of an alloying series Fe1/3Nb1-xTaxS2. Due to the different magnetic orderings of its end members, this alloying series permits the substitutional control of the magnetic ground state of the material system. I will present our thermodynamic measurements and findings.
