The current-voltage characteristics of bulk-sintered YBa2Cu30 7 have been studied in detail. The onset of dissipation indicates that an intergranular critical current can be defined. The magnitudes of the resistance of a single grain boundary and of its critical current are estimated. These estimate
The transport critical current / c of more than 100 samples of high temperature superconductor bulk material was measured as a function of temperature using a contactless magnetic induction method. All samples (mainly YBa2CH3OT\_ ~, but also TI-Ba-Ca-Cu-O and (Bi, Pb)-Sr-Ca-Cu-O) show a temperature
