We have measured the structure of the eld cooled ux line lattice (FLL) in single crystal Nbusing small angle neutron scattering. Augmented by transport and thermodynamic data, a scenariofor the dramatic disordering of the FLL near the peak effect emerges. A precursor to the peakeffect is an hexatic FLL as positional order is lost. As the critical current rises, the orientationaland longitudinal correlation lengths also fall, leading to an amorphous array of lines at the criticalcurrent maximum. [S0031-9007(97)05112-0]
