摘要：

Superconducting films of (Tl(0.5)Pb(0.5))(Sr(0.95)Ba(0.05))(2)(Ca(0.8)Gd(0.2))Cu(2)Oz 1212, approximately 3 mu m in thickness, were fabricated on single-crystalline lanthanum aluminate. The films were practically phase pure and showed excellent in-plane and out-of-plane texture. Critical temperatures of up to 96 K were recorded. Critical current densities of the order of 40 MA m(-2) at 77 K in self-field were measured both by transport and by magnetic studies. Magnetic measurements were made between 5 and 77 K. Microstructure studies were carried out to learn about the effects influencing the critical current density.
