Abstract

We have fabricated superconducting thin films on MgO(100) substrates with nearly pure Tl₂Ba₂Ca₂Cu₃O ₁₀ (2:2:2:3) phase using pulsed laser evaporation and post-annealing. The films had c axes perpendicular to the substrates. Superconducting films with onset temperatures of 125 K and zero resistance at 110 K were obtained. X-ray microprobe fluorescence measurements indicate that a typical composition of films is Tl_0.66Ba_1.77Ca _1.46Cu₃O_x, which is low in Tl compared to that expected for the 2:2:2:3 phase. A typical grain size is greater than 10 μm as revealed by scanning electron microscopy.
