Abstract

We review the magnetic form factor deduced by Delrieu from Gorkov's equation for a Bardeen-Cooper-Schrieffer (BCS) type-II superconductor near its Bc2 phase boundary, i.e., when its magnetization is small. A numerical study of the form factor, field map, and field distribution follows. The characteristics of the transition from the low-temperature BCS to the high-temperature Ginzburg-Landau vortex lattices is studied. The exotic shape of the component field distribution and the form factor at low temperature and as a function of the external field intensity are discussed. Our numerical work should be helpful for the analyzing of small-angle neutron scattering and muon spin rotation vortex-lattice data recorded for BCS superconductors and may be other superconductors in the clean limit.
