Electronic correlations, magnetism and Hund's rule coupling in the ruthenium perovskites SrRuO${}_3$ and CaRuO${}_3$

Hung T. Dang, Jernej Mravlje, Antoine Georges +1

A comparative density functional plus dynamical mean field theory study of the pseudocubic ruthenate materials CaRuO${}_3$ and SrRuO${}_3$ is presented. Phase diagrams are determined f…
