Original Kurzfassung:
Superconducting films of (Tl0.5Pb0.5)(Sr0.95Ba0.05)2(Ca0.8Gd0.2)Cu2Oz 1212, approximately 3 μm 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.
