Zero-field incommensurate spin-Peierls phase with interchain frustration in TiOCl
R. Rückamp, J. Baier, M. Kriener +7
We report on the magnetic, thermodynamic and optical properties of the quasi-one-dimensional quantum antiferromagnets TiOCl and TiOBr, which have been discussed as spin-Peierls com…

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…
