Optical and Electrical Properties of Rare-Earth Substituted Ceramic Samples of the Y-Ba-Cu-O-System
We report the preparation of fully (Nd, Sm, Er, Yb, Pr) and partially (Pr) rare earth (RE) substituted ceramic Y-Ba-Cu-O samples. The cell parameters and the phase purity are characterized by x-ray powder diffraction. The temperature dependence of the electrical resistivity of the samples was determined and the room temperature values are compared with the results of the optical conductivity derived by Kramers-Kronig analysis from IR-reflectivity measurements.
