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