摘要：

Superconducting transition temperatures T of the YBCO film interfaces were measured inductively. It was observed that the interface-T(c) is always higher then the surface-T(c) probably because of the substrate influence. Deposition of the silver over-layer on the film surface enhances also its critical temperature. In the annealed YBCO/Ag bilayers magnetic properties of the interface were observed. This two dimensional structure reminds the layered microstructure of the high-temperature superconductors and one can suppose that enhanced superconductivity of the interfaces is the origin of the high critical temperatures in layered superconductors.
