โœฆ Synopsis

We report about the preparation of lead-free Bi-Sr-Ca-Cu-O thin films of the 2212 phase by laser ablation. We have found an optimal regime for preparation, which makes it possible to produce films with T~0> 80 K andjc (60 K) > 106 A/cm 2 on SrTiO3 substrates. The films are characterized by current transport measurements, RBS, XRD and SEM. We have found a dependence of the film quality on substrate temperature, oxygen partial pressure, pulse repetition rate and post-annealing conditions. First investigations on BSCCO/SrTiO3/BSCCO multilayer systems were performed.

Superconducting thin films of the two CuO2 layer phase in the Pb-doped Bi-Sr-Ca-Cu-O system have been fabricated on (100) MgO and (100) SrTiO 3 substrates by DC magnetron sputtering and ex-situ annealing. The best films were prepared at annealing temperatures just below the melting temperature. On b

Superconducting Bi-Sr-Ca-Cu-O and Bi(Pb)-Sr-Ca-Cu-O f'flms (0.03-2.5t~m) are prepared by deposition onto MgO (200) single crystal substratesin a DC single target sputtering system (pure Ar plasma) and post-deposition anneal. Annealing condition studies show that the Tc values are very dependent on t
