Resumen
Measurements of non-local in-plane resistance originating from transverse vortex-vortex correlations have been performed on a Bi2Sr2CaCu2O8+delta high-T-c superconductor in a magnetic field up to 9 T applied along the crystal c-axis. Our results demonstrate that a rigid vortex lattice does exist over a broad portion of the magnetic field-temperature (H-T) phase diagram, well above the first-order transition (FOT) boundary H-FOT(T). The results also provide evidence for the vortex lattice melting and vortex liquid decoupling phase transitions, occurring above the H-FOT(T). (C) 2002 Elsevier Science Ltd.
