Title: Oscillatory Exchange Coupling in Fe/Cr Multilayers
Published: January 01, 1996
Abstract: First-principles calculations of the reflection probabilities for Fermi surface electrons at Cr/Fe interfaces are used to compute the strength of the oscillatory exchange coupling in Cr/Fe multilayers. These calculations show that critical spanning vectors across the N-centered ellipsoids of the Cr Fermi surface cause the long period coupling for (001), (110), and (211) interfaces. The periods of these spanning vectors, when extracted from the experimental Fermi surface, agree with experimentally measured periods.
