Abstract

re-magnetic-field phase diagram has been constructed. The first-principles electronic structure calculations show that the paramagnetic tetragonal structure of DyFe4Ge2 is stable at high temperatures. The calculations with collinear Dy spins confirm ferrimagnetic orthorhombic DyFe4Ge2 as the ground-state structure.
