Vortex Lattices in Cubic Superconductors

Abstract

Nonlocal corrections to London equations are employed to describe a variety of vortex lattices seen through neutron scattering in cubic crystals of ${\mathrm{V}}_{3}\mathrm{Si}$ with large $\ensuremath{\kappa}$. Within this model the observed symmetries of vortex lattices and their coupling to the underlying crystal are reproduced. Predicted lattice structures are field dependent in agreement with the data.
