Abstract
The (Bi1−x Pb x )2Sr 2Ca 2Cu 3 O y (x = 0.2, 0.4) films were obtained directly on silver substrates by the sedimentation process. The temperature dependencies of the AC susceptibility of the films and bulk materials were measured and analyzed. The critical temperatures of the grains T cg as well as the Josephson junctions T cJ of these films were obtained from the dispersion part of AC susceptibility and they are T cg = 106.5 K, T cJ = 100.2, T cg = 106.1 K, and T cJ = 97 K, respectively. The thickness of these films is of the order of a hundred micrometers. The critical currents were derived from the absorption part of AC susceptibility using the Bean’s critical state model. The temperature dependencies of the critical currents were analyzed using the Ginzburg–Landau strong coupling limit approach.
