USE OF HIGH-TC SUPERCONDUCTING ELECTRODES FOR LEAD LANTHANUM ZIRCONIUM TITANATE CERAMICS

Lead lanthanum zirconium titanate (PLZT) 9.5/65/35 samples were electroded with BSCCO and YBCO superconductor materials. Extensive interaction was obtained between the PLZT and the YBCO, and very low interaction was observed between the BSCCO and the PLZT. The BSCCO superconductor on the PLZT substrate maintained its superconducting properties at liquid nitrogen temperature. The apparent dielectric constant of the PLZT was influenced by the electroding materials. Domain switching was found to be influenced by the electrode materials at low temperature. The BSCCO electroded samples showed the highest polarization switching rate among the samples electroded by different materials.
