Present study is devoted to ab initio investigation of MnBi2Te2Se2 and VBi2Te2Se2 compounds. It is shown that these compounds hav the electronic structure features typical for a topological insulator. However, these compounds are antiferromagnetically ordered phases. Such antiferromagnetic topological insulators (AFM Tl) were predicted in 2010 by Mong et al, and these compunds turn out to satisfy all requirements to be AFMTls.
