Originální abstrakt
Ab initio and Monte Carlo simulations are employed to estimate isotropic exchange interactions and Curie temperature of A2BB ' O6 oxides (A alkaline-earth metal or transition metal and B, B ' transition metals). The dominant (B-B') interactions are antiferromagnetic (AFM) between the first and second nearest neighbors (NN), and these interactions strengthen as the magnetic moments of B and B' increase. Third and fourth NN interactions (B-B or B '-B ') are always weaker than the others. Although B '-B ' interactions induce magnetic frustration if they are AFM, the ground state is always ferrimagnetic. The Curie temperature range spans from 290 K for Sr2FeOsO6 to 640 K for Be2FeOsO6. Our study reveals that, in the search for a desired high Curie temperature of A2BB ' O6 oxides, an A cation should be as small as possible, and B, B ' magnetic moments should be as large as possible.
