Jf. Mackay et al., ELEMENT-SPECIFIC MAGNETIZATION OF BURIED INTERFACES PROBED BY DIFFUSE-X-RAY RESONANT MAGNETIC SCATTERING, Physical review letters, 77(18), 1996, pp. 3925-3928
The magnetization of buried interfaces and its relationship to interfa
cial roughness is probed for Co films and Co/Cu multilayers using diff
use x-ray resonant magnetic scattering, a method in which the average
diffusely scattered x-ray intensity is compared with the component tha
t reflects magnetic scattering. The comparison demonstrates that the b
oundary between magnetic and nonmagnetic layers is smoother than the i
nterfacial roughness, with short-wavelength roughness less effective i
n magnetic scattering than longer-wavelength roughness.
