Abstract

The magnetic properties of materials based on two-dimensional transition-metal dichalcogenides (TMDC), namely bulk Fe1/4TaS2 compound as well as TMDC monolayers with deposited Fe films, have been investigated by means of first-principles DFT calculations. Changing the structure and the composition of these two-dimensional systems resulted in considerable variations of their physical properties. For the considered systems the Dzyaloshinskii-Moriya (DM) interaction has been determined and used for the subsequent investigation of their magnetic structure using Monte Carlo simulations. Rather strong DM interactions as well as large vertical bar D-01 vertical bar/J(01) ratios have been obtained in some of these materials, which can lead to the formation of skyrmionic structures varying with the strength of the applied external magnetic field.
