Abstract

The critical current density, magnetic hysteresis and relaxation of the magnetisation have been measured on a 1000 ÅYBa₂Cu₃O_7-δ-film in a field perpendicular to the plane of the film. The film was made by co-deposition in a UHV triple e -gun system, using BaF₂ as one of sources. The results have been interpreted in terms of flux pinning and creep of curved flux lines with locally different pinning energies.
