Inelastic neutron scattering from the vortex lattice in type-II superconductors. I

Abstract

The inelastic neutron scattering from the vortex lattice in dirty type-II superconductors is considered. In the high-field region, the correlation function for the local magnetization is given in terms of the fluctuation propagator of the superconducting order parameter. In particular it is shown that the Fourier transform of the correlation function for the local magnetization diverges as /q ⊥−G i /−2, when the transverse transfered momentumq ⊥ approaches the reciprocal lattice vectorG i of the Abrikosov lattice. This term gives rise to tails around each Bragg peak in the inelastic neutron-scattering cross section.
