    Magnetic properties of thermally treated Fe/Al multilayers

    No full text
    Fe/Al multilayers, e-beam evaporated and thermally treated in UHV, were analyzed by Mössbauer and magnetic measurements. Al diffusion along grain boundaries into Fe gives rise to solid solution and paramagnetic compounds at interfaces. By decreasing Fe thickness, the grain size decreases and the surrounding paramagnetic compounds increase, justifying the changes in hysteresis loops and reversible susceptibility

    Size dependent magnetic properties in Fe/Al multilayers

    No full text
    Morphological and magnetic properties of Fe/Al ultra-thin film multilayers are studied as a function of Fe layer thickness by means of transmission electron microscopy, conversion electron Mössbauer spectroscopy, alternating gradient force magnetometry and AC susceptometry. With decreasing iron layer thickness, aluminum diffusion causes a progressive loss of periodicity and the formation of particulate systems. The magnetic behavior progressively evolves from ferromagnetic to superparamagnetic
