Abstract
The trapped flux distribution in thin wafers of both polycrystalline and gr anular superconductors having large demagnetization and edge barriers of di fferent heights is measured by means of polarized neutrons. It is shown tha t the nature of the critical state in polycrystalline wafers, unlike that i n a ceramic wafer, is not described by the Bean model. (C) 1999 American In stitute of Physics.
