Element-specific magnetic moments in Fe/V superlattices are studied using x-ray magnetic circular dichroism (XMCD). Superlattices are simultaneously deposited with the epitaxial orientations (100), (211), and (110), to explore the orientation dependence of these moments. The layer-averaged vanadium moments are antiparallel to those of the Fe and are 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: ) in qualitative agreement with recent calculations. In contrast to calculations, the magnitudes of the V moments fall on a universal curve for the three orientations.

The wave vector dependence of Rayleigh and higher order Sezawa elastic waves in single crystalline epitaxial face-centered-cubic (fcc) Co layers are measured by Brillouin light scattering at room temperature. The dispersion of the mode velocities allows the independent elastic constants to be determined for this cubic phase of cobalt. These results compare very favorably to previous determinations of the elastic constants measured above 700 K from the high-temperature fcc phase of pure Co. Deviations from theoretical estimates are discussed.
