New paper on “Excitonic Magnetism in Ruthenates”
Excitonic Magnetism at the intersection of Spin-orbit coupling and crystal-field splitting Teresa Feldmaier, Pascal Strobel, Michael Schmid, Philipp Hansmann, Maria Daghofer Excitonic magnetism involving superpositions of singlet and triplet states is expected to arise for two holes in strongly correlated and spin-orbit coupled t2g orbitals. However, uncontested material examples for its realization are rare. Applying the Variational Cluster Approach to the […]Excitonic Magnetism at the intersection of Spin-orbit coupling and crystal-field splitting Teresa Feldmaier, Pascal Strobel, Michael Schmid, Philipp Hansmann, Maria Daghofer Excitonic magnetism involving superpositions of singlet and triplet states is expected to arise for two holes in strongly correlated and spin-orbit coupled t2g orbitals.
