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…
Magnon mode selective spin transport in compensated ferrimagnets
Joel Cramer, Er-Jia Guo, Stephan Geprägs +10
We investigate the generation of magnonic thermal spin currents and their mode selective spin transport across interfaces in insulating, compensated ferrimagnet/normal metal bilaye…
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…
