Résumé
Cette étude est une mise au point de la théorie des ondes de spin et des effets physiques liés à ces ondes. On y montre que la condition aux limites à la surface m x = my = 0 permet l'excitation des ondes de spin par un champ uniforme de fréquence radio. Waring et Jarrett, ainsi que Seavey et Tannenwald, ont observé ces excitations. Abstract. - A review is given of the theory of spin waves and of the principal physical effects associated with spin,waves. It is shown that the boundary condition m x = my = 0 at the surface permits the excitation of spin waves by a uniform rf field. These excitations have been observed by Waring and Jarrett and by Seavey and Tannenwald.
