Abstract

We review the magnetic form factor deduced by Delrieu from the 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 analysing of small angle neutron scattering and muon spin rotation vortex-lattice data recorded for BCS superconductors and maybe other superconductors in the clean limit.

Comments

A mistake for the form factor normalization was made in our original draft. In this version Eqs.: (25), (31), (32), (35), (D5), (D6), and (E4) are corrected by including the missing factor 1/4\pi. Second sentence of Sec. VII referring to Eq. (E4) was also corrected
