A shear transformation has previously been shown to account for the discontinuities or jumps in the crystallographic thermal expansion coefficients across the normal to superconducting transition temperature. The crystallographic stress dependence of the superconducting transition temperature is sho
Effects of oxidative chlorination on tetragonal YBa2Cu307\_x are studied. After reaction with gaseous chlorine at 415-435 K nonsuperconducting YBa2Cu3Or.~ becomes superconducting. The formation of BaO2 and CUC12.2 H20 is shown by X-ray diffraction analysis. The C1/element ratio in the chlorinated-pr
