Abstract
Measurements of non-local in-plane resistance originating from transverse vortex–vortex correlations have been performed on a Bi 2Sr 2CaCu 2O 8+ δ 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).
