✦ Synopsis

Unusual resistivity behavior of single-crystalline BizSrzCaCu20s+o in magnetic fields up to 6 T is reported with special emphasis on the role of superconducting fluctuation effects that are connected with the short coherence length in this highly two-dimensional electronic system. The field-induced resistivity in the superconducting state depends only on the relative orientation of the applied field with respect to the crystallographic axes, and is not related to Lorentz forces which are in general considered to be the main cause of the driving force for flux motion.
