Abstract

Distribution of a local field B(x) on the surface of Bi2Sr2CaCu2O8+d single crystal and its time dependence are measured using a micro Hall-probe array with 7 elements. From these data, the activation energy dependence on B(x) and on the current density J are estimated. The three-dimensional mapping of U(B, J) in B, J and U space gives us information on spatial behavior of U(B, J) in the sample.
