Strain dependence of magnetism in transition-metal phosphorus trichalcogenides — •Yang-Jun Lee1,2,3, Tae Yun Kim2, and Cheol-Hwan Park1,2,3 — 1Department of Physics and Astronomy, Seoul National University, Seoul 08826, Korea — 2Center for Correlated Electron Systems, Institute for Basic Science, Seoul 08826, Korea — 3Center for Theoretical Physics, Seoul National University, Seoul 08826, Korea
Few-layer transition-metal phosphorus trichalcogenides (TMPX3) are two-dimensional (2D) antiferromagnetic materials, which have recently attracted attention because they can realize interesting 2D magnetic phenomena; they are considered materials whose magnetism can be described by the Heisenberg model, Ising model, or XY model depending on the transition metal ion. In this talk, we present the strain effects on the magnetism of TMPX3 compounds obtained from first principle calculations. Also, we will talk about the change in the symmetry and the magnetic model due to the strain.
