Exchange-enhanced Ultrastrong Magnon-Magnon Coupling in a Compensated Ferrimagnet
Lukas Liensberger, Akashdeep Kamra, Hannes Maier-Flaig +7
The ultrastrong coupling of (quasi-)particles has gained considerable attention due to its application potential and richness of the underlying physics. Coupling phenomena arising…
Perpendicular magnetic anisotropy in insulating ferrimagnetic gadolinium iron garnet thin films
H. Maier-Flaig, S. Geprägs, Z. Qiu +5
We present experimental control of the magnetic anisotropy in a gadolinium iron garnet (GdIG) thin film from in-plane to perpendicular anisotropy by simply changing the sample temp…
Note: Derivative divide, a method for the analysis of broadband ferromagnetic resonance in the frequency domain
Hannes Maier-Flaig, Sebastian T. B. Goennenwein, Ryo Ohshima +4
Broadband ferromagnetic resonance (bbFMR) spectroscopy is an established experimental tool to quantify magnetic properties. Due to frequency-dependent transmission of the microwave…
Temperature dependent magnetic damping of yttrium iron garnet spheres
Hannes Maier-Flaig, Stefan Klingler, Carsten Dubs +5
We investigate the temperature dependent microwave absorption spectrum of an yttrium iron garnet sphere as a function of temperature (5 K to 300 K) and frequency (3 GHz to 43.5 GHz…
Tunable magnon-photon coupling in a compensating ferrimagnet - from weak to strong coupling
H. Maier-Flaig, M. Harder, S. Klingler +7
We experimentally study the magnon-photon coupling in a system consitsing of the compensating ferrimagnet gadolinium iron garnet (GdIG) and a three-dimensional microwave cavity. Th…
Gilbert damping of magnetostatic modes in a yttrium iron garnet sphere
Stefan Klingler, Hannes Maier-Flaig, Carsten Dubs +5
The magnetostatic mode (MSM) spectrum of a 300m diameter single crystalline sphere of yttrium iron garnet is investigated using broadband ferromagnetic resonance (FMR). The indi…
Spin pumping in strongly coupled magnon-photon systems
Hannes Maier-Flaig, Michael Harder, Rudolf Gross +2
We experimentally investigate magnon-polaritons, arising in ferrimagnetic resonance experiments in a microwave cavity with a tuneable quality factor. To his end, we simultaneously…
