Microwave magnon damping in YIG films at millikelvin temperatures
Sandoko Kosen, Arjan F. van Loo, Dmytro A. Bozhko +2
Magnon systems used in quantum devices require low damping if coherence is to be maintained. The ferrimagnetic electrical insulator yttrium iron garnet (YIG) has low magnon damping…
Determination of the spin Hall angle in single-crystalline Pt films from spin pumping experiments
Sascha Keller, Laura Mihalceanu, Matthias R. Schweizer +12
We report on the determination of the spin Hall angle and the identification of the role of the interface roughness for the inverse spin Hall effect (ISHE) in ultra-clean, defect-r…
Temperature dependent relaxation of dipole-exchange magnons in yttrium iron garnet films
Laura Mihalceanu, Vitaliy I. Vasyuchka, Dmytro A. Bozhko +5
Low energy consumption enabled by charge-free information transport, which is free from ohmic heating, and the ability to process phase-encoded data by nanometer-sized interference…
Spin-pumping through a varying-thickness MgO interlayer in Fe/Pt system
Laura Mihalceanu, Sascha Keller, Jochen Greser +7
The spin-pumping mechanism is probed through a tunnelling MgO interlayer in Fe/Pt bilayers. We show by ferromagnetic resonance technique and spin-pumping experiments that spin curr…
