Abstract

High-resolution small-angle neutron scattering studies of the vortex lattice (VL) in YNi2B2C allow us to separate Bragg scattered intensities from the multi-domain VL that exists for Bparallel toc. The first-order 45degrees reorientation of the VL at a field H-1 is broadened by weak vortex pinning and characterised by a redistribution of domain populations between the low- and high-field vortex structures through the transition with no continuous distortion between the two phases. As nonlocal effects become weaker with increasing temperature, H-1(T) decreases while the field at which the VL becomes square, H-2 (T), increases. The nature of the high-field rhombic VL (H-1 < H < H-2) close to H-c2 (T) is discussed. (C) 2003 Elsevier Science B.V. All rights reserved.
