Abstract

The qz-dependent sign of the X-ray charge-magnetic interference diffuse scattering observed from an Fe-Gd multilayer is found to be due to rough internal magnetic interfaces in the Gd layers. The internal magnetic roughness is correlated with the charge roughness of the Fe-Gd interface. Born-approximation calculations using a fractal interface model show that the internal and Fe-Gd interfaces have similar magnetic roughness, as evidenced by the similar in-plane cut-off lengths of charge-magnetic height-height correlation functions.
