Abstract = {{O 1s x-ray absorption study of the Mott insulator Ca2RuO4 shows that the
   orbital population of the 4d t(2g) band dramatically changes with
   temperature. In addition, spin-resolved circularly polarized
   photoemission study of Ca2RuO4 shows that a substantial orbital angular
   momentum is induced in the Ru 4d t(2g) band. Based on the experimental
   results and model Hartree-Fock calculations, we argue that the
   cooperation between the strong spin-orbit coupling in the Ru 4d t(2g)
   band and the small distortion of the RuO6 octahedra causes the
   interesting changeover of the spin and orbital anisotropy as a function
   of temperature.}},
