“…Once the chemical distribution is obtained a periodic Anderson model ͑in collinear approach͒ is used 19 to derive the magnetic map and the total energies of configurations with FM and AF couplings between the Fe slabs through the Cr spacer. In dependence on the mutual ordering of the magnetic moments in initial ͑non-self-consistent͒ state, parallel or antiparallel ordering of magnetic moment in the first and second Fe slabs can be obtained after self-consistency.…”

The influence of interface alloying on the phase and strength of the short-range oscillations of the interlayer exchange coupling ͑IEC͒ in the Fe/Cr multilayers is analyzed on the basis of stochastic modeling of interdiffusion with subsequent self-consistent calculations of magnetic structure. We explain the experimentally observed behavior of the IEC in the Fe/Cr/Fe trilayers grown on Fe whisker. Experiments with artificially alloyed FeCr layer deposited at the top of the Cr spacer allow the determination of intermixing parameters for the Fe/Cr and for the Cr/Fe interfaces.

“…It produces a very narrow interface, where only two atomic layers in the superlattice contain atoms of both elements [28,29]. Such a structure of the interface does not agree with experimental results on magnetic moments and hyperfine fields (hff) in most metallic multilayers [30][31][32].…”

We present an atomistic model of interface alloying that presupposes exchange of adatoms with substrate atoms and floating of adatoms on the upper layers during deposition. Due to the existence of a preferred direction (the growth direction), the chemical profile near the interface proves to be asymmetrical. The floating algorithm combined with self-consistent calculations of atomic magnetic moments is used as a model for interpreting Mössbauer data obtained from 57 Fe-enriched interfacial tracer layers in Fe/Cr(001) superlattices. The superlattices were grown at different temperatures in order to modify their interface roughness. A linear correlation between calculated moment peaks and observed distinct magnetic hyperfine fields was found. Our experimental samples exhibit larger intermixing than the simplified theoretical model we used. The experimental giant magnetoresistance ratio was observed to increase with the decreasing fraction of certain 57 Fe atoms located in the interfacial region. Therefore, bulk scattering from impurity atoms appears to provide the main contribution to the giant magnetoresistance in Fe/Cr. Moreover, our theoretical results clarify the dependence of the short-wavelength period of interlayer coupling on the interface roughness in Fe/Cr.

“…The PAM has two approaches: collinear, where only parallel and antiparallel orientations of the magnetic moments exist, and noncollinear, with consideration of an arbitrary orientation of the magnetic moments relative to a global axis [8,9]. It is shown that PAM is effective in studying Fe/Cr [10] and Fe/V [11] multilayers with a large number of considered atoms in the supercell, and allows one to handle the nonhomogeneous structures at the surface and interface.…”
