Query: Vortex Lattice in Bi_{2}Sr_{2}CaCu_{2}O_{8+\delta} Well Above the
  First-Order Phase-Transition Boundary   Measurements of non-local in-plane resistance originating from transverse
vortex-vortex correlations have been performed on a
Bi_{2}Sr_{2}CaCu_{2}O_{8+\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 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).
