We report on the magnetic, thermodynamic, and optical properties of the quasi-one-
dimensional quantum antiferromagnets TiOCl and TiOBr, which have been discussed as …

The discovery of intrinsic 2D magnetic materials has opened up new opportunities for
exploring magnetic properties at atomic layer thicknesses, presenting potential applications …

Strong spin-orbit interaction in the two-dimensional compound Sr 2 IrO 4 leads to the
formation of J eff= 1/2 isospins with unprecedented dynamics. In Raman scattering a …

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 by …

Temperature-dependent x-ray diffraction of the low-dimensional spin-1∕ 2 quantum magnet
TiOBr shows that the phase transition at T c 2= 47.1 (4) K corresponds to the development of …

We report on a detailed single crystal x-ray diffraction study of the unconventional spin-
Peierls compound TiOCl. The intermediate phase of TiOCl is characterized by an …

We studied the transmittance and reflectance of the low-dimensional Mott-Hubbard insulator
TiOCl in the infrared and visible frequency range as a function of pressure. The strong …

Measurements of the heat capacity C (T, H) of the one-dimensional quantum magnet TiOCl
are presented for temperatures 2 K< T< 300 K and magnetic fields up to 5 T. Distinct …

The sequence of phase transitions and the symmetry of, in particular, the low temperature
incommensurate and spin-Peierls phases of the quasi-one-dimensional inorganic spin …

We have studied the S= 1∕ 2 quasi-one-dimensional antiferromagnet TiOCl using single
crystal x-ray diffraction and inelastic x-ray scattering techniques. The Ti ions form staggered …
