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 magnetic moments maps and the interlayer couplings are obtained directly from self-consistent tight-binding band structure calculations allowing to discuss the results in the proximity magnetism framework. We show that the bilinear-biquadratic expression for the coupling energy ts nicely the calculated interlayer couplings curves in all considered cases.
