Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
