Experimental study of conductivity in Bi2Sr2CaCu2O8+x crystals by means ofmultiterminal measurements

Resistivity measurements have been demonstrated to be a powerful tool for t he investigation of vortex dynamics. Multiterminal measurements have been w idely used to analyze the correlation of Vortices across the planes (pseudo -Giaever experiment). We present a large set of measurements in different c onfigurations for various magnetic field strengths and orientations, both i n the normal state and in the mixed state. We will discuss a large class of experimental features relating them to the correlation between the CuO pla nes. (C) 2000 Elsevier Science B.V. All rights reserved.
