Abstract

Superconducting Tl-Ba-Ca-Cu-O thin films 0.2-1.0 μm thick have been prepared on MgO(100) and SrTiO₃(100) substrates by dc diode sputtering using a single oxide target. Films containing primarily the Tl ₂Ba₂Ca₁Cu₂O₈ phase were obtained with a T_c (R=0) at 102 K and a transport J_c of 10⁴ A/cm² at 90 K. For the nearly pure phase Tl ₂Ba₂Ca₂Cu₃O₁₀ films, the T_c's (R=0) are higher at 116 K and the transport J _c's at 100 K are of 10⁵ A/cm². Both types of films show a strong preferred orientation with the c axis perpendicular to the film plane. The rocking curve of the Tl₂Ba₂Ca ₂Cu₃O₁₀ films is 0.32°wide and the typical grain size is over 10 μm.
