摘要：
Laser deposited superconducting thin films of GdBa2Cu3O7-delta (Gd-123) and GdBaSrCu3O7-delta (GBSCO) are compared with respect to their electrical properties, surface morphology, and structure. The maximum zero-resistance temperatures of Gd-123 and GBSCO films on MgO substrates are T-C0 = 93.5 K and 78 K, respectively. The critical current density of Gd-123 films is crucially influenced by their granular morphology, whereas the superconducting properties of GBSCO films are mainly determined by the concentration and distribution of oxygen.
