T. Schuster et al., FLUX-PENETRATION OF MELT-PROCESSED YBA2CU3O7-DELTA - DIRECT OBSERVATION OF ANISOTROPY, Journal of applied physics, 74(5), 1993, pp. 3307-3311
Flux distributions observed on melt-processed YBa2Cu3O7-delta samples
are presented with the external magnetic field oriented parallel and p
erpendicular to the c axis using the high-resolution Faraday effect te
chnique. In this way, flux penetration along and across the Cu-O plane
s is observed directly. The measured flux density profiles allow a det
ermination of the different critical current densities and show the in
fluence of intrinsic pinning.
