Enhanced Interlayer Exchange Coupling in Co/Fe/MgO/Fe(001)

We investigate the bilinear and biquadratic interlayer exchange coupling in Co/Fe/MgO/Fe(001). Samples are grown through molecular beam epitaxy and the interlayer exchange coupling is measured through magneto-optic Kerr effect along wedge samples. By varying the location of Fe impurities between the interface and middle of the MgO spacer, we find that the couplings are enhanced and are dependen...

Interlayer Exchange Coupling in Fe/MgO/Fe Magnetic Tunnel Junctions

Interlayer Exchange Coupling

The extensive research done on interlayer exchange coupling in transition metal multilayers has resulted in a deep understanding of this coupling and a remarkable agreement between theoretical results and measurements. The coupling between two magnetic layers separated by a non-magnetic spacer layer is mediated by the electrons of the spacer layer. The coupling, which oscillates in sign as a fu...

AB INITIO STUDY OF ELECTRIC TRANSPORT AND INTERLAYER EXCHANGE COUPLING IN Fe/Si/Fe SYSTEMS

We present a first principles study of the magnetoresistance (MR) perpendicular to the planes of atoms and the interlayer exchange coupling (IEC) in Fe/Si/Fe trilayers. In both cases the dependence on the number of spacer layers is investigated, whereby the spacer thickness ranges between 3 and 21 Å for the IEC and extends to 33 Å for the MR in order to obtain the asymptotic behavior.
