Flux distributions observed on melt-processed YBa2Cu 3O7-δ samples are presented with the external magnetic field oriented parallel and perpendicular to the c axis using the high-resolution Faraday effect technique. In this way, flux penetration along and across the Cu-O planes is observed directly. The measured flux density profiles allow a determination of the different critical current densities and show the influence of intrinsic pinning.
