Abstract
Direct observations and measurements of spatial magnetic flux distribu tions on the surfaces of YBaCuO superconducting thin films and thin si ngle crystals realized under application of external magnetic field an d transport current are accomplished using magneto-optical indicators. These investigations are compared with theoretical calculations yield ing critical current densities. Special attention is paid to the influ ence of defects on the magnetic properties. Furthermore, specific feat ures of flux penetration into flat superconductors are revealed.
