Abstract
We have calculated the electronic structure for CaRuO3 and SrRuO3 within first principles electronic structure calculations. We find that the experimentally observed ferromagnetic state is favoured in the case of SrRuO3, while our calculations also suggest that no state with long range magnetic order will be stabilised for CaRuO3. Mapping the total energies for different magnetic configurations to an extended Heisenberg model, we find that a localized spin model is found to be invalid to describe the magnetic state of these systems.
