Abstract

Using ab-initio methods we study structural, electronic and magnetic properties of two dimensional compounds with stoichiometry M₂N₃ (M-metal, N=S,Se,Te). Our study shows that structures with Cr, Ti, and Mn are stable, with significant binding energy. Also, such structures are semiconductors with narrow band gaps. We also show that Cr₂Se₃, Cr₂Te₃ and Mn₂Te₃ have considerable magnetic moments. The negative values of magnetic anisotropy energy suggest, that these materials can maintain ferromagnetic ordering in non-zero temperatures with estimated Curie temperatures in the range of 30-55 K.
