(TlPbBi)-(SrBa)-Ca-Cu-O superconducting films obtained by electrodeposition process
초록
We have performed the electrochemical method to fabricate high temperature superconducting (TlPbBi) -(SrBa)-Ca-Cu-O films. The precursors of the superconducting sample were codeposited at a periodic pulsed-potential cycle (1 second at -4V and 1 second at -1V) on a silver substrate. The variation of structure, microstructure and element were analysed by ICP and SEM techniques. The specimens were consisted predominantly of the Tl-1212 phase and have a transition temperature of 80~87 K in low magnetic field. It was showed that each grain has the stoichiometric ratio of
