Magnetization temperature dependence in Fe/Cr superlattices

View publication

Abstract

We report the temperature dependence of the saturation magnetization, Ms(T), of Fe(t)/Cr(40 Å) superlattices grown on MgO(1 0 0) and MgO(1 1 0) and its variation with Fe-layer thickness (5 Å <t<80 Å). The structure was characterized by X-ray diffraction. Ms(t) vs. T, as measured by DC magnetization and ferromagnetic resonance, show a large interface effect. The origins of this effect are discussed. © 2002 Elsevier Science B.V. All rights reserved.
