Superconductor Science and Technology, 21 (2008), S. 1 - 4.

Superconducting films of (Tl_0,5Pb_0,5)(Sr_0,95Ba_0,05)₂(Ca_0,8Gd_0,2)Cu₂O_z 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.
