Abstract / Description:Raman scattering is used to observe pronounced electronic excitations
around 230 meV-well above the two-phonon range-in the Mott insulators
LaTiO3 and YTiO3. Based on the temperature, polarization, and photon
energy dependence, the modes are identified as orbital excitations. The
observed profiles bear a striking resemblance to magnetic Raman modes
in the insulating parent compounds of the superconducting cuprates,
indicating an unanticipated universality of the electronic excitations
in transition metal oxides.
