Oscillatory exchange coupling in Fe/Cr multilayers.
First-principles calculations of the reflection probabilities for Fermi surface electrons at Cr/Fe interfaces are used to compute the strength of the oscillatory exchange coupling in Cr/Fe multilayers. These calculations show that critical spanning vectors across the N -centered ellipsoids of the Cr Fermi surface cause the long period coupling for (001), (110), and (211) interfaces. The periods...
متن کاملSpin-flop coupling and rearrangement of bulk antiferromagnetic spins in epitaxial exchange-biased Fe/MnPd/Fe/IrMn multilayers
The role of bulk antiferromagnetic spins on exchange bias was investigated in interface spin-flop coupled Fe/MnPd bilayers and Fe/MnPd/Fe/IrMn multilayers. Magnetic measurement of the bilayers showed that the exchange bias saturated at a uniquely large critical thickness, ∼300 Å, with a spin reorientation transition simultaneously observed. Field cooling of the multilayer, with parallel or anti...

متن کاملAsymmetric magnetization reversal in exchange-biased hysteresis loops
Polarized neutron reflectometry is used to probe the in-plane projection of the net-magnetization vector M--> of polycrystalline Fe films exchange coupled to twinned (110) MnF (2) or FeF (2) antiferromagnetic (AF) layers. The magnetization reversal mechanism depends upon the orientation of the cooling field with respect to the twinned microstructure of the AF, and whether the applied field is i...
متن کاملAsymmetric magnetization reversal in exchange biased polycrystalline F/AF bilayers
This paper describes a model for magnetization reversal in polycrystalline Ferromagnetic/Antiferromagnetic exchange biased bilayers. We assume that the exchange energy can be expanded into cosine power series. We show that it is possible to fit experimental asymmetric shape of hysteresis loops in exchange biased bilayer for any direction of the applied field. The hysteresis asymmetry is discuss...
