Abstract
We discuss the tilted vortex lattice in layered type-II superconductors, using the anisotropic London theory. We pay particular attention to the crossover region between the low-B regime, in which vortex chain structure dominates, and the high-B region, where the chain structure has disappeared. This crossover region can be quite large, in some cases spanning several decades in magnetic field. We use both numerical calculation and simple physical arguments.
