【 摘 要 】
We have performed extensive small-angle neutron scattering (SANS) diffraction studies of the vortex lattice in single crystal YNi2B2C for $B||c$. High-resolution SANS, combined with a ï¬eld-oscillation vortex lattice preparation technique, allows us to separate Bragg scattered intensities from two orthogonal domains and accurately determine the unit cell angle, ð›½. The data suggest that upon increasing ï¬eld there is a ï¬nite transition width where both low- and high-ï¬eld distorted hexagonal vortex lattice phases, mutually rotated by 45°, coexist. The smooth variation of diffracted intensity from each phase through the transition corresponds to a redistribution of populations between the two types of domains.
