    Specular and Off-Specular X-Ray Scattering as Quantitative Structural Probes of Multilayers. Application to MN/IR(111) Superlattices

    Diffuse scattering of X rays is a particularly useful tool for studying interface and surface defects in single layer films. We have extended this technique to the study of multilayers. The samples are Mn/Ir(1...

    Unusual Magnetic Behaviour of BCT Fe Thin Films Evidenced by 57Fe Mössbauer Spectrometry

    Unusual magnetic behaviours occur in thin Fe films grown on Ir(100) by Molecular Beam Epitaxy. Four different magnetic sites are actually observed in these layers by Conversion Electron Mössbauer Spectrometry....

    Interrelation Between Structure and Magnetism of Ultra-Thin Mn Films Epitaxially Grown on (001) BCC Fe

    In this paper, the interrelation between structural and magnetic properties of ultra-thin Mn films epitaxially grown on (001) bcc Fe is studied. The Mn growth and in-plane structure were controlled by electron...

    Magnetic Properties of FEXMN1-X/IR(100) Superlattices.

    We have produced pseudomorphic FexMn1-x/Ir(100) superlattices having different stoichiometry (0.8 ≥ x ≥ 0.3). The alloy crystalline structure is body centered tetragonal with a c/a ratio between 1.18 and 1.26. Ir...

    Structural properties and thermal stability of Fe/Al2O3 multilayers

    Iron/alumina multilayers have been deposited on sapphire wafers using RF magnetron sputtering. To study the interdiffusion, the multilayers were annealed in a tubular furnace under a 10−7 mbar vacuum, and the sam...

    Magnetic and Structural Properties of Iron Nitride thin Films Obtained by Argon-Nitrogen Reactive Radio-Frequency Sputtering

    Fe-N thin films have attracted considerable attention because they are potential candidates for magnetic recording with their large saturation magnetization and their good corrosion resistance1. It has even been ...

    Effect of Ion Irradiation on the Artificial Structure and the Interlayer Coupling of Copper-Cobalt Multilayers

    Structural defects like local ferromagnetic short-circuits are responsible for large reductions of the intrinsic interlayer coupling in the case of antiferromagnetically (AF) coupled multilayers (ML). We have ...

    Modification of Magnetic Coupling in Antiferromagnetically Coupled Bilayers Due to the Existence of Ferromagnetic Pin Holes.

    We have calculated numerical simulations and analytical solutions of the influence of a pin hole on the magnetization curves of multilayer systems. The magnetization curves we obtained can be described by a bi...

    New BCT Iron Phase In (100) Felr Superlattices

    In this paper, the synthesis of a new structure of iron in (100) Felr superlattices grown by Molecular Beam Epitaxy is reported. Two-dimensional growth up to 4 planes at 400K occurs, as shown by RHEED oscillat...

    Evidence for Spin Polarization of Metallic Copper in Co/Cu and Fe/Cu Multilayers

    Magnetic circular x-ray dichroism measurements on Co/Cu and Fe/Cu multilayers at the K edge of copper show that the 4p-states of copper are significantly spin-polarized by the adjacent magnetic layers. In relatio...

    Magnetic Properties of Fe/Ru and Fe/Ir Superlattices with Short Periodicity

    We present new results on the magnetic properties of constrained, iron base, good quality, single-crystalline superlattices, Fe/Ru and Fe/Ir. It is shown that in the first case there are two magnetically dead ...

    Atomic Structure and Growth Mode of Fe/Ir Superlattices with Short Periodicity

    FeIr superlattices with short periodicities are realised by Molecular Beam Epitaxy. Ir on (1120) sapphire and Fe on (111) Ir growths are studied in situ by electron diffraction. Like FeRu superlattices, a new ...
