Iron (Fe) and europium monoxide (EuO) were multilayered by an ultra-hi
gh vacuum deposition method. X-ray diffraction and Eu-151 Mossbauer me
asurements have confirmed the formation of a single phase EuO. An anom
alous temperature dependence of the magnetization suggests antiferroma
gnetic coupling at the interface and spin-glass-like behavior in the F
e layers.
