摘要
An array of miniature Hall sensors has been utilized to measure the spatial distribution and time evolution of the local induction in a thin YBa2Cu3O7-x film at the remanent state, before and after the application of a de transport current. As a result of transport current the induction peak is shifted from the center of the sample, indicating an inhomogeneous current distribution. Transport current markedly changes the spatial distribution of the electric field and the relaxation rate, creating a "dynamic neutral line" where the electric field is maximum: and the relaxation rate is zero.
