Summary: 4MF09 1
Abstract--The direct observation of the field at the surface of
SC samples when the field is applied or in the remanent state,
allows the observation of the current distribution along the
magnetization loop by using inverse problem solvers.
Furthermore, the mean value of the field reflects well the
magnetization of the sample obtaining the magnetization loop
taken in account both possibilities, the In Field Hall Mapping
technique, thus, has revealed as a powerful characterization
technique. This technique can be improved by including the
critical state simulation, giving so a very complete way to
characterize artificially welded superconducting samples, thus
allowing the identification of the critical current flowing through
the surface between domains as is the case of the effect of welded
bulks. Some examples of the characterization procedures are
reported.
