Effective spin Hamiltonian model for superexchange interaction between rare earth ions in rare earth elpasolite crystals.
The fine structure of zero phonon lines in the electronic absorption spectra of lanthanide ion systems is interpreted by an effective spin Hamiltonian model. The splittings of several cm-1 observed for lanthanide ions with interionic separations near 1 nm in elpasolite lattices are attributed to superexchange interactions.
