TL;DR: In this paper, the authors measured the structure of the FLL in single crystal with small angle neutron scattering and showed that as the critical current rises, the orientational and longitudinal correlation lengths also fall, leading to an amorphous array of lines at the criticalcurrent maximum.
Abstract: We have measured the structure of the field cooled flux 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]
