Abstract
Three different regimes of thermally activated dissipation behaviour w ere determined in the superconducting (Bi,Pb)(2)Sr2Ca2Cu3Ox thin film in dependence on the external magnetic field. The negative electrostat ic field applied to the film surface has been found to increase the ac tivation energy of flux creep in relatively low magnetic fields. The u pper critical magnetic field determined from resistive measurements in creases in the vicinity of superconducting transition temperature unde r the influence of the electrostatic field.
