Abstract
A scanning Hall probe has been applied for observing the spatial distr ibution of the trapped magnetic field in superconducting Ag-sheathed B i2223 tapes. Tapes with a transport J(c) of 1192-10 084 A cm(-2) have been imaged with a spatial resolution of 100 mu m. Non-uniform field-p rofiles are often observed and attributed to some imperfections in the oxide core. Hall-probe micrography is thus quite useful for non-destr uctive examination of Ag-sheathed Bi2223 tapes.
