Abstract
The relaxation time of long-wavelength magnons is calculated for the mechanism involving two-magnon scattering by dislocations. The results could be used to study the broadening of the spin wave resonance spectrum by dislocations in thin ferromagnetic films.
Résumé
On a calculé le temps de relaxation des magnons aux grandes longueurs d'ondes en tenant compte du mécanisme de diffusion de deux magnons par les dislocations. On applique les résultats obtenus à l'étude de l'élargissement des raies du spectre de résonance des ondes de spin par les dislocations dans les couches minces ferromagnétiques.
