Calculated angular dependence of the interlayer couplings in Fe/Cr superlattices having imperfect interfaces Daniel StoefflerCorresponding Author Contact Information <#m4.cor*>, E-mail The Corresponding Author and Clara Cornea Institut de Physique et de Chimie des Matériaux de Strasbourg, UMR 7504 du CNRS, Groupe d'Etude des Matériaux Métalliques, 23 rue du Loess F-67037, Strasbourg, France Available online 6 November 2001. Abstract We present calculations of the non-collinear magnetic structure in Fe/Cr superlattices having imperfect interfaces modeled by considering atomic steps in the Cr layers and Fe/Cr interfacial ordered compounds. The interlayer couplings are obtained directly from self-consistent tight binding band structure calculations. We show that the bilinear–biquadratic expression for the coupling energy fits nicely the calculated interlayer couplings curves.

Calculated (symbols) and fitted (solid lines) coupling energies EC as a function of Δstraight theta, small theta, GreekM for all Fe/Cr multilayers considered in this work having a Cr thickness between 4 and 5 atomic layers. The two graphs at right correspond to a zoom of the graph at left for small energies. Table 1.
