PROPERTIES OF LASER-DEPOSITED TMBASRCU3O7-DELTA THIN-FILMS

Single-phase thin films of superconducting TmBaSrCu3O7-delta have been deposited on (100) MgO substrates by pulsed-laser deposition from mul ti-phase targets. The morphology of these films is similar to that of TmBa2Cu3O7-delta films. The differences in the electrical properties a re discussed in terms of intrinsic differences between the two compoun ds. With TmBaSrCu3O7-delta films critical temperatures of T-c0 = 72 K and critical current densities of j(c)(57 K) = 10(6) A/cm(2) have been achieved.
