Description
Summary:Profiles of the magnetic field distribution around monofilamentary Bi-2223/Ag tape have been studied by one-dimensional electron paramagnetic resonance (EPR). The profiles have been taken for zero field cooling and field cooling procedures scanning the EPR probe over the tape surface at liquid helium temperature. The measurements have been performed for an original Bi-2223/Ag tape placed in an external magnetic field perpendicular to the flat surface of the sample. The obtained results indicate that magnetic flux profiles resemble those observed in thin films or slabs. The profile taken for an artificial structure made by drilling a hole in the tape exhibits a field distribution somewhat different from the one predicted by theory.
