Flux Penetration of Melt-Processed YBa sub 2 Cu sub 3 O sub 7-- delta : Direct Observation of Anisotropy

Flux distributions observed on melt-processed YBa sub 2 Cu sub 3 O sub 7-- delta 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 plane...

Description
Summary:Flux distributions observed on melt-processed YBa sub 2 Cu sub 3 O sub 7-- delta 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.
