Abstract

The ternary rare-earth based systems exhibit interesting physical and structural properties. Lots of them, eg. chromium germanides were experimentally studied concerning their magnetic properties [1] and up to our knowledge they were never studied theoretically explaining nature of their magnetic behaviour. In the presented work the magnetic and electronic properties of RCrGe2 and RCr0.3Ge2 (R=Tb, Dy, Ho or Er) were investigated theoretically applying plane-wave DFT/PBE methodology. The computational investigations were performed for the crystallographic structure with the space group Cmcm. The stoichiometry of the rare-earth chromium germanides compounds has also significant eect on the electronic properties of compounds. The
