Spin transport and magnetic proximity effect in CoFeB/normal metal/Pt trilayers
Simon Häuser, Matthias R. Schweizer, Sascha Keller +7
We present a study of the damping and spin pumping properties of CoFeB/X/Pt systems with and . We show that the total damping of the CoFeB/Pt systems is stron…
Low damping magnetic properties and perpendicular magnetic anisotropy with strong volume contribution in the Heusler alloy Fe1.5CoGe
Andres Conca, Alessia Niesen, Günter Reiss +1
We present a study of the dynamic magnetic properties of TiN-buffered epitaxial thin films of the Heusler alloy FeCoGe. Thickness series annealed at different temperatures…
Separation of the two-magnon scattering contribution to damping for the determination of the spin mixing conductance
Andres Conca, Sascha Keller, Matthias R. Schweizer +2
We present angle dependent measurements of the damping properties of epitaxial Fe layers with MgO, Al and Pt capping layers. Based on the preferential distribution of lattice defec…
Evolution of the interfacial perpendicular magnetic anisotropy constant of the CoFeAl/MgO interface upon annealing
Andres Conca, Alessia Niesen, Günter Reiss +1
We investigate thickness series of films of the Heusler alloy CoFeAl in order to study the effect of annealing on the interface with a MgO layer and on the bulk magnetic proper…
CoFeAlB alloy with low damping and low magnetization for spin transfer torque switching
A. Conca, T. Nakano, T. Meyer +2
We investigate the effect of Al doping on the magnetic properties of the alloy CoFeB. Comparative measurements of the saturation magnetization, the Gilbert damping parameter an…
Measurements of the exchange stiffness of YIG films by microwave resonance techniques
Stefan Klingler, Andrii V. Chumak, Tim Mewes +6
Measurements of the exchange stiffness and the exchange constant of Yttrium Iron Garnet (YIG) films are presented. The YIG films with thicknesses from 0.9 m to 2.6 m…
Epitaxial Co2Cr0.6Fe0.4Al thin films and magnetic tunneling junctions
A. Conca, M. Jourdan, H. Adrian
Epitaxial thin films of the theoretically predicted half metal Co2Cr0.6Fe0.4Al were deposited by dc magnetron sputtering on different substrates and buffer layers. The samples were…
Towards a full Heusler alloy showing room temperature half-metallicity at the surface
M. Cinchetti, J. -P. Wüstenberg, M. Sánchez Albaneda +4
In this article we investigate the surface spin polarization in a 100 nm Co2Cr0.6Fe0.4Al (CCFA) film grown ex situ epitaxially on MgO(100) with a 10 nm Fe buffer layer by means of…
Epitaxy of thin films of the Heusler compound Co2Cr0.6Fe0.4Al
A. Conca, M. Jourdan, C. Herbort +1
Epitaxial thin films of the highly spin polarized Heusler compound Co2Cr0.6Fe0.4Al are deposited by dc magnetron sputtering. It is shown by XRD and TEM investigations how the use o…
