Mechanical twinning in quartz rocks: in situ experiments at stress and during...
Previous experiments at ENGIN-X (Wenk et al. 2007) established that quartz rocks undergo mechanical twinning if stressed above 100 MPa. The amount of twinning is highly... -
O/N-distribution in host lattices for rare-earth doped phosphors in light emi...
Nitridosilicates and oxonitridosilicates (sions) gain more and more importance as host lattices for rare-earth doped phosphors in light emitting diodes. By means of... -
Superconductivity induced changes in the ferromangetic order of Y(1-x)PrxBa2C...
By polarized neutron reflectometry we want to investigate the magnetic field profile in Y(1-x)PrxBa2Cu3O7/La(2/3)Ca(1/3)MnO3 high-Tc superconductor/ferromagnet superlattices. In... -
Influence of the cation disorder on the magnetic properties of underdoped cup...
We want to isolate the effects of doping, charge localization and local distortion on the transition from insulating antiferromagnet to superconducting metal in YBCO. We choose... -
Insulator to metal transition in TiOCl at high pressures
We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our...
