Abstract

Bi-Pb-Sr-Ca-Cu-O superconducting films were prepared by metalorganic deposition on single LaAIO₃(100) substrates using acetate solution of starting composition Bi_2.46Pb_0.74Sr_2.0Ca_2.2Cu_3.2O_y. The films were prepared by repeating the process of coating and decomposition( at 700°C for 30 min ) 5 times and finally sintering at 855°C for 12 hours. The values of T_co and J_c of 1.5 μm thick films were 98K and 1.2×10⁴A/cm²(64K, OT) respectively. The result of x-ray pole figures has shown that these films were epitaxial through a good lattice match of LaAlO₃ substrates. ICP analysis showed that mole ratio of Pb was lower than 0.1 in the film on MgO(as mole ratio of Cu=3.2).
