ABSTRACT
We report on the first iron based amorphous alloy formed by the process of solid state reaction. Amorphous iron zirconium was observed to result from thermal anneals of layered crystalline elemental constituents. Starting material was electron beam evaporated with about 50 monolayers of each constituent per layer, which results in an average composition of Fe61Zr39 and a compositional wavelength of 22 nm. Thermal anneals at 623 K were performed in vacuum, and x-ray diffraction was used to determine the structure. A calculated metastable free energy diagram shows the reaction is driven by a large thermodynamic driving force (several kcal/mole).

    For the exchange biased polycrystalline FeNi/FeMn bilayers, we systematically studied the ferromagnet (FM) magnetization reversal pathway dependent recovery effect of training using a vector vibrating sample magnetometer. Our experimental results show unambiguously that the well-known recovery...

    We report the studies of tuning the exchange bias at ferromagnetic Fe/metamagnetic FeRh bilayer interfaces. Fe/FeRh(111) bilayers show exchange bias in the antiferromagnetic state of FeRh while no exchange bias occurs at Fe/FeRh(001) interface. The contrasting results are attributed to the spin...

    Nanocrystalline Fe-X-N thin films (with doping X=0, 3.1 at.% Al, 1.6 at.% Zr), were deposited using reactive ion beam sputtering. Magnetization study reveals that the deposited films exhibit a perpendicular magnetic anisotropy. Thermal stability of the films was investigated systematically and...
