摘要：

Review of superconducting (T-c, H-c2(T), J(c)), electron transport R-s(T), surface (XPS, UPS) and structural (XRD, RBS) properties of thin films of a novel superconductor BaNbO3 - x on different substrates is presented. Superconducting films have been obtained when grown on the Al2O3 with T-c = 14 K, J(c) approximate to 1 x 10(4) A cm(-2) and large H-c2(0) = 28 T. At the same time, films on NdGaO3 exhibit behavior typical to granular superconductors. (C) 2000 Elsevier Science B.V. All rights reserved.
