Résumé
Nous examinons la diffraction des neutrons thermiques par le réseau des vortex d'un supraconducteur de deuxième espèce. Nous montrons que l'ancrage des vortex non seulement introduit un élargissement des pics de Bragg mais aussi une composante diffuse dans la première zone de Brillouin qui, à champ élevé, est plus intense que la composante de Bragg.
Abstract
The diffraction of neutrons from the imperfect vortex lattice of a type-II superconductor is investigated. It is found that flux pinning leads not only to a broadening of the Bragg reflections but also to diffuse scattering into the first Brillouin zone, which at high fields exceeds Bragg scattering.
