Antiferromagnetic magnon pseudospin: Dynamics and diffusive transport
Akashdeep Kamra, Tobias Wimmer, Hans Huebl +1
We formulate a theoretical description of antiferromagnetic magnons and their transport in terms of an associated pseudospin. The need and strength of this formulation emerges from…
Observation of Antiferromagnetic Magnon Pseudospin Dynamics and the Hanle effect
Tobias Wimmer, Akashdeep Kamra, Janine Gückelhorn +5
We report on experiments demonstrating coherent control of magnon spin transport and pseudospin dynamics in a thin film of the antiferromagnetic insulator hematite utilizing two Pt…
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…
Spin transport in a magnetic insulator with zero effective damping
Tobias Wimmer, Matthias Althammer, Lukas Liensberger +5
Applications based on spin currents strongly profit from the control and reduction of their effective damping and their transport properties. We here experimentally observe magnon…
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…
Non-local magnon transport in the compensated ferrimagnet GdIG
Kathrin Ganzhorn, Tobias Wimmer, Joseph Barker +8
We study the diffusive transport of magnons through the compensated ferrimagnetic insulator Gd3Fe5O12 (GdIG). The magnons are injected and detected electrically in a non-local meas…
