ABSTRACTThe magnetic interlayer exchange coupling in Fe/Si-based thin film structures employing sputtered multilayers with variations of Si-alloyed Fe for the magnetic layers and Fe-alloyed Si spacers, as well as wedge-shaped MBE-grown Fe/Si/Fe sandwich samples has been systematically studied. From structural and magnetic analysis it is concluded that ultrathin Si and FexSi100-x (x < 50) spacer layers transform into a crystalline iron suicide with a composition close to Fe50Si50. The exchange coupling mediated by this metallic suicide is antiferromagnetic and depends on the spacer thickness in an exponential, i.e. non-oscillatory, manner with a universial characteristic decay length of 3–4 Å at room temperature. This observation can be qualitatively explained within the framework of a recent coupling theory on the premise that the FeSi interlayer has the metastable CsCl(B2)-structure.

AbstractGiant magnetoresistance values exceeding 65% at room temperature are reported in antiferromagnetically coupled Co/Cu multilayers grown on Fe buffer layers using magnetron sputter deposition. For such samples the saturation fields exceed 10 kOe. However by taking advantage of the rapid decrease of the Co interlayer magnetic exchange coupling with increasing Cu spacer layer thickness, large magnetoresistance values exceeding 35% can be obtained at room temperature for saturation fields of just a few hundred oersted.

AbstractWe show that oscillatory interlayer exchange coupling of thin magnetic layers through metals is a general phenomenon present in almost all the transition and noble metals. Surprisingly the period of the oscillations is approximately the same, about 10Å, in all these metals with the sole exception of Cr for which the period is significantly longer. The strength of the coupling varies systematically throughout the 3d, 4d and 5d transition metals increasing exponentially along each of the transition metal periods and increasing from the 5d to 4d to 3d periods. These results appear to be inconsistent with simple Ruderman-Kittel-Kasuya-Yosida (RKKY) based models.
