Abstract
We review the results of small neutron scattering studies of the superconducting flux line lattice (FLL) in the borocarbide RNi2B2C superconductors. The first experiments on these compounds with magnetic field parallel to the c axis discovered a square FLL in the majority of the phase diagram, with a smooth transition to a hexagonal symmetry at field below ~ 1 kOe. These results proved to be in agreement with the predictions of a model by V. Kogan et al. which includes non-local corrections to the London model due to the Fermi surface anisotropy of the borocarbides. A very different transition is observed when the applied magnetic field is perpendicular to the c axis. In this case, a discontinuous reorientation between two hexagonal vortex arrangements is observed at a well defined line in the magnetic phase diagram.
