Abstract

An experimental study has been made of the electric field effect in an electrode/insulator/superconductor system on the critical current (Ic) and the current-voltage (I-V) characteristics at 77 K of large, c-axis-textured (BiPb)2Sr2Ca2Cu3Ox superconductor bars. In strong electric fields (120 MV/m), the current and conductivity of bars at current I > Ic increased. The electric field effect was reversible and was observed in various field orientations with respect to the pressing direction of the bars. New peculiarities of the field effect were observed in the presence of current-voltage hysteresis.
