Abstract

Antiferromagnetically coupled (Co17A°Re5A°)×15 superlattices were deposited simultaneously onto glass and Si substrates, with an intervening Re buffer layer. Samples grown on glass show sharper interfaces than those grown on Si. This effect reflects on Magnetoresistance, Magnetization, Rutherford backscattering, and hyperfine field results. The influence of the Re buffer layer thickness and annealing temperature on these properties is discussed.
