Abstract

The authors present a numerical investigation into the magnetically ordered state of Ca₂RuO₄ and establish it as an excitonic antiferromagnet. While the excitonic character coexists with strong orbital polarization, spin-orbit coupling leads to some deviations from perfect orbital order and from a pure spin scenario.
