Magnetic x-rayscattering study of interfacial magnetism in a Gd-Y superlattice

Abstract
The modulation in the magnetic moment and in the interplanar spacing (strain) in the superlattice [Gd21 Y21]×40 has been determined by use of synchrotron and rotating-anode x-ray sources. The average moment appears to decrease in the interfacial regions, and the width of the strain interface increases with decreasing temperature.
