Y. Song et al., INFLUENCE OF ANNEALING ON THE RAYLEIGH SURFACE-WAVE VELOCITY IN METALLIC MULTILAYER FILMS, Journal of magnetism and magnetic materials, 126(1-3), 1993, pp. 203-206
Elastic and structural properties in sputtered Ag/Co and Au/Co multila
yers have been studied via Brillouin scattering and X-ray diffraction
as a function of modulation wavelength. Softening of the Rayleigh soun
d velocity due to interfacial strain has been observed for both of the
as-deposited films. However the softening is very sensitive to the mo
dification of the interfacial structure caused by thermal annealing.
