Abstract
We have reported the Raman scattering and infrared absorption results on a t2g orbital ordered Ca2RuO4. At 10Â K, a strong and clear peak was observed in Raman scattering near 1360Â cmâ1 with xâ²xâ² geometry. In contrast to optic phonon modes, the peak does not show any frequency shift but rapidly decreases with increasing temperature. In addition, the peak is not observed in infrared absorption measurement. By comparing the previous Raman scattering results for several transition metal oxides, we have discussed the possible origins and ambiguities of the intriguing peak in Ca2RuO4.
