Imaging of current induced Néel vector switching in antiferromagnetic MnAu
S. Yu. Bodnar, M. Filianina, S. P. Bommanaboyena +6
The effects of current induced Néel spin-orbit torques on the antiferromagnetic domain structure of epitaxial MnAu thin films were investigated by X-ray magnetic linear dichro…
c-Axis tunneling in YBa2Cu3O7-δ/PrBa2Cu3O7-δsuperlattices
J. C. Martinez, A. Schattke, M. Jourdan +2
In this work we report c-axis conductance measurements done on a superlattice based on a stack of 2 layers YBa2Cu3O{7-δ} and 7 layers PrBa2Cu3O{7-δ} (2:7). We find that these qua…
Efficient metallic spintronic emitters of ultrabroadband terahertz radiation
T. Seifert, S. Jaiswal, U. Martens +18
Terahertz electromagnetic radiation is extremely useful for numerous applications such as imaging and spectroscopy. Therefore, it is highly desirable to have an efficient table-top…
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…
Néel Spin Orbit Torque driven antiferromagnetic resonance in MnAu probed by time-domain THz spectroscopy
N. Bhattacharjee, A. A. Sapozhnik, S. Yu. Bodnar +11
We observe the excitation of collective modes in the THz range driven by the recently discovered Néel spin-orbit torques (NSOT) in the metallic antiferromagnet MnAu. Tempera…
Magnetic anisotropies and magnetization reversal of the CoCrFeAl Heusler compound
J. Hamrle, S. Blomeier, O. Gaier +3
Magnetic anisotropies and magnetization reversal properties of the epitaxial Heusler compound CoCrFeAl (CCFA) deposited on Fe and Cr buffer layers are studied.…
