We present the results of measurements of the thermal conductivity of the quasi one-dimensional spin S=1/2 chain compound SrCuO_2 in the temperature range between 0.4 and 300 K along the directions parallel and perpendicular to the chains. An anomalo

We report measurements of the specific heat and the thermal conductivity of the model Heisenberg spin-1/2 chain cuprate Sr$_{2}$CuO$_{3}$ at low temperatures. In addition to a nearly isotropic phonon heat transport, we find a quasi one-dimensional ex

We report the observation of a frequency ($\omega $) and temperature (T) -dependent loss peak in $\chi''$ and accompanying dispersion in $\chi'$ from microwave (2-18GHz) measurements of the complex susceptibility $\tilde{\chi}(\omega, T)=\chi'+i\chi'

Andreev reflections have been studied at the interface between a gold tip and La2−xSrxCuO4 (x=0.11,0.12) single crystals, along the (110) direction. The shape of the I(V) characteristic has been analyzed within the framework of the theory of Tanaka

We analyze microwave cavity perturbation methods, and show that the technique is an excellent, precision method to study the dynamic magnetic and dielectric response in the $GHz$ frequency range. Using superconducting cavities, we obtain exceptionall

Centimetric size single crystals of SrCuO 2 , Sr 2 CuO 3 and Sr 14 Cu 24 O 41 were grown by a floating zone technique associated with an image furnace. Growth conditions are presented together with data relative to assessment of crystal perfection, c
