Electronic structure and interlayer exchange coupling in Fe/Cr superlattices

Abstract

We use self-consistent total-energy supercell band calculations to study the electronic structure of b.c.c. Fe/Cr magnetic multilayers. We find that, for n layers of Cr sandwiches between three layers of Fe, alternate Fe layers prefer ferromagnetic order for n = 3 and antiferromagnetic order for n = 4, 5, 6, and 7. The magnetic coupling is shown to result from an interplay between direct «d-d» hybridization of Fe and Cr atoms, and indirect exchange coupling through the «sp» electrons. © 1991 IOP publisher Ltd.
