“…The reason is that producing a high-quality MTJ with a thin barrier is a very complicated task. There are only few reports of measurements of IEC in MTJs [6], [7] and [8]. The results obtained in these experiments signifi cantly differ from the theoretical predictions [2], [3], [4] and [5], both in the magnitude and the sign of IEC.…”

“…al. [8] have observed non-oscillatory decay of IEC in the FM-insulator multilayer with the increasing insulating spacer layer thickness. Similar nonoscillatory decay of the FM-insulator multilayer with the insulating spacer layer thickness has also been found from in the theoretical calculation by introducing the complex Fermi surface [9,10].…”

A direct correlation is seen between the coercive field (H C ) and the magnetic-fielddependent resistivity (MR) in SrMnO 3 /SrRuO 3 superlattices of perpendicular magnetic anisotropy. The magnetoresistance shows a sharp jump at H c for in-plane current and the out-of-plane magnetic field. Both H C and high-field MR also oscillate with the thickness of the SrMnO 3 spacer layers separating the metallic ruthenate. Since the spacer in these superlattices has no mobile carriers to facilitate an oscillatory coupling, we attribute the observed behavior to the spin-polarized quantum tunneling of electrons between the ferromagnetic layers and antiferromagnetically ordered t 2g spins of SrMnO 3 . 1 prellier@ensicaen.fr

“…Ferromagnet/semiconductor (FM/SC) heterostructures seem to be especially promising for application in spintronic devices. The most widely investigated systems are Fe/Si heterostructures owing to their very strong antiferromagnetic (AF) interlayer coupling [1][2][3][4][5][6]. The antiferromagnetic (AF) coupling in an amorphous Fe/Si/Fe trilayer evaporated onto amorphous substrate was first observed in 1992 by Toscano et al [6].…”

We review selected results concerning the interlayer exchange coupling in Fe/SixFe1−x , Fe/Ge and Co/Si layered structures. Among the ferromagnet/semiconductor systems, Fe/Si structures are the most popular owing to their strong antiferromagnetic interlayer coupling. We show that such interaction depends not only on semiconducting sublayer thickness, but also on deposition techniques and on the chemical composition of the sublayer as well. In similar heterostructures e.g. Fe/Ge, antiferromagnetic coupling was observed only in ion-beam deposited trilayers at low temperatures. In contrast, in Fe/Ge multilayers deposited by sputtering, no such coupling was found. However, when the Ge is partially substituted by Si, antiferromagnetic interlayer coupling appears. For Co/Si multilayers, we observed a very weak exchange coupling and its oscillatory behavior. The growth of Co on Si occurs in an island growth mode. The evolution of magnetic loop shapes can be successfully explained by the interplay between interlayer coupling and anisotropy terms.
