Magnetic and Structural Analysis of Ultra-Thin Magnetic Films, Multilayers, and Superlattices by Mössbauer Spectroscopy

In the study of thin films and surfaces as well as the examination of superlattices, the careful characterization of these systems including their structural, Magnetic, transport, and other properties has been absolutely crucial to the advancement of the field. As Means of sample preparation have progressed, techniques for evaluating the flatness, continuity, crystallinity, etc. of thin films and surfaces have become ever more necessary to understand the resulting magnetic and electronic properties. Because iron is often a constituent of Magnetic thin films and because the isotope 57Fe shows a strong Mossbauer Effect over a wide temperature range the technique of Mossbauer Spectroscopy offers much to the study of surfaces, thin films, and superlattices.
