“…We note that our results agree with published results obtained by use of break junctions 28 and film break junctions 29 and also of point contacts 30 and microbridgelike junctions. 31 spectively, were prepared by mixing appropriate amounts of T1203, Ba(N03)2, CaO, and CuO.…”

We report on a study of single-phase (superconducting) YBa2Cu;}07 and (nonconducting) Y2BaCu05 and mixed phases of these compounds in bulk and film samples and on an investigation of ceramic bulk material of the homologous series Tl2Ba2CanCun+i02n+6-We describe preparation and structural characterization by x-ray diffraction analyses and further characterization by electric, magnetic, tunnel junction, and Raman scattering studies, and we present results of far-infrared reflectivity measurements. In a theoretical analysis we relate the phonon structure of reflectivity spectra to geometric structure of a metallic network, with holes filled with nonconducting material. The influence of superconductivity on reflectivity is also investigated.
