Abstract

Samples of nominal composition (Pb_0.5Cd_0.5) (Sr_2-xBa_x) (Ca_0.5Y_0.5)Cu₂O_y (0≤x≤0.5) synthesised at 920°C in air are investigated. XRD shows the samples to exhibit the tetragonal 1212-phase. The lattice parameters, the width of the Raman peak for the apical-0(2) vibration mode and the infrared absorption peak for the 0(3) vibration mode, all increase with increasing Ba doping level. In the doping range (0.0≤x≤0.5), there is a transition from insulator to superconductor. The Raman shift and the wavenumber of the infrared absorption for the phonon peaks appear to change regularly.
