Conference paper


Thin films of YBa2Cu3Oy and Bi2Sr2Ca2Cu3Oy superconductors were formed by a thermal decomposition technique using organometallic precursor solutions. Dependence of resistivity on temperature showed the Tc(onset) at 93 K and Tc(zero) at 90 K with the YBa2Cu3Oy film on yttria stabilized zirconia substrate, and the Tc(onset) at 115 K and Tc(zero) at 80 K with the Bi2Sr2Ca2Cu3Oy film on MgO(100) substrate. The X-ray diffraction patterns showed that the both YBa2Cu3Oy and Bi2Sr2Ca2Cu3Oy films were strongly oriented along the c-axis perpendicular to the substrate.
