Abstract

Using the technique of polarized-neutron reflectometry, we have studied the magnetic moment distribution in the interfacial region of an epitaxial film consisting of 97 Å Y(0001) atop 1000 Å Gd(0001). At T = 151 K, with an 80 gauss field applied parallel to the surface (basal plane), we observe two distinct ferromagnetic regions: the Gd bulk and a layer with reduced magnetic moment at the Y/Gd interface. Above the bulk Curie temperature, at T = 295 K, we observe no net magnetization in either the bulk or the interface.
