Crystal field effects on spin pumping
Adam B. Cahaya, Alejandro O. Leon, Gerrit E. W. Bauer
"Spin pumping" is the injection of spin angular momentum by a time-dependent magnetization into an adjacent normal metal proportional to the spin mixing conductance. We study the r…
Indirect coupling of magnons by cavity photons
Babak Zare Rameshti, Gerrit E. W. Bauer
The interaction between two magnetic spheres in microwave cavities is studied by Mie scattering theory beyond the magnetostatic and rotating wave approximations. We demonstrate tha…
Voltage control of interface rare-earth magnetic moments
Alejandro O. Leon, Adam B. Cahaya, Gerrit E. W. Bauer
The large spin orbit interaction in rare earth atoms implies a strong coupling between their charge and spin degrees of freedom. We formulate the coupling between voltage and the l…
Theory of magnon-mediated tunnel magneto-Seebeck effect
Benedetta Flebus, Gerrit E. W. Bauer, Rembert A. Duine +1
The tunnel magneto-Seebeck effect is the dependence of the thermopower of magnetic tunnel junctions on the magnetic configuration. It is conventionally interpreted in terms of a th…
Nonlocal magnon-polaron transport in yttrium iron garnet
L. J. Cornelissen, K. Oyanagi, T. Kikkawa +5
The spin Seebeck effect (SSE) is observed in magnetic insulator|heavy metal bilayers as an inverse spin Hall effect voltage under a temperature gradient. The SSE can be detected no…
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…
