Oscillation period of the interlayer coupling in epitaxial Fe/{sub 1-x}V{sub x}(100) and (211) superlattices.

Description

The microscopic origin of the 18-{angstrom} period in the oscillatory interlayer exchange coupling of Fe/Cr( 100) and (211) superlattices is investigated by alloying the Cr spacer with V to alter its Fermi surface. The addition of V increases or decreases in size the various Fermi surface calipers that are candidates for governing the oscillation period, such as those that span the ellipse, lens, octahedron, and nested sheets. Epitaxial sputtered superlattices of (100) and (211) orientation were grown and characterized via magnetoresistance measurements as a function of spacer layer thickness for different V-doping levels. A small decrease of the oscillation period ... continued below

Description

The microscopic origin of the 18-{angstrom} period in the oscillatory interlayer exchange coupling of Fe/Cr( 100) and (211) superlattices is investigated by alloying the Cr spacer with V to alter its Fermi surface. The addition of V increases or decreases in size the various Fermi surface calipers that are candidates for governing the oscillation period, such as those that span the ellipse, lens, octahedron, and nested sheets. Epitaxial sputtered superlattices of (100) and (211) orientation were grown and characterized via magnetoresistance measurements as a function of spacer layer thickness for different V-doping levels. A small decrease of the oscillation period is found experimentally which strongly implicates the N-centered ellipse as the origin of the 18-{angstrom} period in Fe/Cr superlattices.
