Electrically induced angular momentum flow between separated ferromagnets
Richard Schlitz, Matthias Grammer, Tobias Wimmer +7
Converting angular momentum between different degrees of freedom within a magnetic material results from a dynamic interplay between electrons, magnons and phonons. This interplay…
Influence of low-energy magnons on magnon Hanle experiments in easy-plane antiferromagnets
Janine Gückelhorn, Akashdeep Kamra, Tobias Wimmer +5
Antiferromagnetic materials host pairs of spin-up and spin-down magnons which can be described in terms of a magnonic pseudospin. The close analogy between this magnonic pseudospin…
Magnon transport in /Pt nanostructures with reduced effective magnetization
Janine Gückelhorn, Tobias Wimmer, Manuel Müller +4
For applications making use of magnonic spin currents damping effects, which decrease the spin conductivity, have to be minimized. We here investigate the magnon transport in an yt…
Quantitative comparison of magnon transport experiments in three-terminal YIG/Pt nanostructures acquired via dc and ac detection techniques
Janine Gückelhorn, Tobias Wimmer, Stephan Geprägs +3
All-electrical generation and detection of pure spin currents is a promising way towards controlling the diffusive magnon transport in magnetically ordered insulators. We quantitat…
Anomalous spin Hall angle of a metallic ferromagnet determined by a multiterminal spin injection/detection device
Tobias Wimmer, Birte Coester, Stephan Geprägs +4
We report on the determination of the anomalous spin Hall angle in the ferromagnetic metal alloy cobalt-iron (CoFe, CoFe). This is accomplished by measuring the spin…
Current direction anisotropy of the spin Hall magnetoresistance in nickel ferrite thin films with bulk-like magnetic properties
Matthias Althammer, Amit Vikam Singh, Tobias Wimmer +5
We utilize spin Hall magnetoresistance (SMR) measurements to experimentally investigate the pure spin current transport and magnetic properties of nickel ferrite (NiFe2O4,NFO)/norm…
