Electrochemical synthesis of Tl-based high T-c single-phase superconductorthin films

Co-deposition of the Tl-based superconductors using electrodeposition techn ique was successfully carried out. Different processing parameters such as deposition potential, current density, deposition period etc were studied. The Tl-based alloyed thin films were deposited at a constant potential of - 1.25 V with respect to SCE electrode onto silver substrates and oxidized a t 850 degrees C in oxygen atmosphere. The samples thus prepared showed supe rconducting behaviour below 122.5 K and the critical current density was 1. 5 x 10(3) A/cm(2). Electrochemical synthesis of Tl-based high T-c single-ph ase superconductor thin films Is also reported.
