摘要：

Multiterminal measurements have been made on Bi2Sr2CaCu2O8 crystals to investigate the vortex dimensionality at the fields and temperatures where the first-order transition takes place in the vortex lattice. A sharp hysteretic transition is seen in transport properties with current injected either parallel or perpendicular to the ab planes. The data indicate that both resistivity components disappear concurrently, and the melting and c-axis decoupling transitions occur simultaneously at a sublimation transition of the vortex lattice.
