ABSTRACT

The unique chemical and physical properties of 3d transition metals play an important role in determining the magnetic behavior of artificial structures such as thin films and multilayers.

Since in 3d metals the appearance of a non-zero magnetic moment is associated with the presence of unbalanced minority-spin holes in the empty electronic states, spin polarized empty states spectroscopies, such as spin resolved Inverse Photoemission (IPE) and Absorbed Current (AC) spectroscopies can be successfully applied to the study of such systems. Here we present the results obtained in the study of V and Cr thin films on Fe(001), Cr thin films on Ag and Fe-Cr-Fe and FeO-Cr-Fe multilayers.
