Resonant inelastic x-ray scattering operators for t2g orbital systems

Resonant inelastic x-ray scattering operators for t2g orbital systems We derive general expressions for resonant inelastic x-ray scattering (RIXS) operators for t2g orbital systems, which exhibit a rich array of unconventional magnetism arising from unquenched orbital moments. Within the fast collision approximation, which is valid especially for 4d and 5d transition metal compounds with short core-hole lifetimes, the RIXS operators are expressed in terms of total spin and orbital angular momenta of the constituent ions. We then map these operators onto pseudospins that represent spin-orbit entangled magnetic moments in systems with strong spin-orbit coupling. Applications of our theory to such systems as iridates and ruthenates are discussed, with a particular focus on compounds based on d4 ions with Van Vleck-type nonmagnetic ground state. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review B American Physical Society (APS)
