X-ray absorption spectroscopy on layered cobaltates Na_xCoO_2
T. Kroll, M. Knupfer, J. Geck +7
Measurements of polarization and temperature dependent soft x-ray absorption have been performed on Na_xCoO_2 single crystals with x=0.4 and x=0.6. They show a deviation of the loc…

Optical study of orbital excitations in transition-metal oxides
R. Rückamp, E. Benckiser, M. W. Haverkort +13
The orbital excitations of a series of transition-metal compounds are studied by means of optical spectroscopy. Our aim was to identify signatures of collective orbital excitations…
