Distribution of captured flux at the Josephson medium; Raspredelenie zakhvachennogo potoka v dzhozefsonovskoj srede

Technical Report:

Abstract

The patterns of a distribution of inner fields in the ceramic sample Y-Ba-Cu-O are obtained by means of the neutron polarized beam scanning. The information about the Josephson screening currents is extracted from these patterns for the fields smaller than a low critical field of grains. Dependencies of the screening currents versus the inner field B near the sample boundary and in its depth are distinguished with one another. Maximum accessible values of screening current densities are corresponded to a critical current whose linear fashion depends on the field B. From this dependence an initial critical current density J{sub 0} and a characteristic spatial scale are extracted. 14 refs.; 11 figs.
