Toyohiko J. Konno*, Takenori Nakayama**, Bruce M. Clemens* and Robert Sinclair* *Department of Materials Science and Engineering, Stanford University Stanford, CA 94305, U.S.A. "**MaterialsResearch Laboratory, Kobe Steel, Ltd., Kobe, 651, Japan ABSTRACT We investigated structural and magnetic properties of Fe/Zr multilayer films using highresolution transmission electron microscopy, X-ray diffraction and vibrating sample 80A, the interface region between the Fe and magnetometry. For films with wavelength (A) _> Zr layers exhibits a 15-20A thick amorphous structure. The magnetization curves of these films showed a monotonous decrease in the saturation magnetizations with A, whose trend is well explained by a simple asymptotic model that assumes the interface amorphous layer to be nonferromagnetic. Films with A_
