Indications of weak electronic correlations in SrRuO3 from first-principles calculations
Physical Review B 86, (6),pp 064441/1-5 (2012)
We provide, by a detailed first-principles investigation, evidence for weak electronic correlations in SrRuO3. The magnetism in SrRuO3, in terms of the equilibrium magnetization and critical temperature, is well described by the generalized gradient approximation. Including Hubbard-type correlations results in worse agreement with experiment.
