Abstract
We carried out a LDA+DMFT study of perovskite ruthenates SrRuO3 and CaRuO3, compounds which have been discussed in great detail in recent literature. Our results reproduced the observed mass enhancements and magnetic properties, and were in reasonable agreement with the measured photoemission spectra. Our calculations produced rather different coherence temperatures for SrRuO3 and CaRuO3, providing a possible explanation for the observed differences between these compounds. We also present k-resolved spectra for the sake of comparison with future angle-resolved photoemission experiments.
