INDUCED-V MOMENTS IN FEV(100), (211), AND (110) SUPERLATTICES STUDIEDUSING X-RAY MAGNETIC CIRCULAR-DICHROISM

Element-specific magnetic moments in Fe/V superlattices are studied us ing x-ray magnetic circular dichroism (XMCD). Superlattices are simult aneously deposited with the epitaxial orientations (100), (211), and ( 110), to explore the orientation dependence of these moments. The laye r-averaged vanadium moments are antiparallel to those of the Fe and ar e larger than those observed in alloys with similar composition. The V moments decay monotonically and relatively slowly with distance from the Fe interface (exponential decay length: approximate to 3.0 Angstro m) in qualitative agreement with recent calculations. In contrast to c alculations, the magnitudes of the V moments fall on a universal curve for the three orientations.
