Imaging non-standing spin-waves in confined micron-sized ferromagnetic structures under uniform excitation
Santa Pile, Thomas Feggeler, Taddäus Schaffers +10
A non-standing character of directly imaged spin-waves in confined micron-sized ultrathin permalloy (Ni\textsubscript{80}Fe\textsubscript{20}) structures is reported along with evi…
Dynamics of the magnetoelastic phase transition and adiabatic temperature change in Mn1.3Fe0.7P0.5Si0.55
M. Fries, T. Gottschall, F. Scheibel +7
The adiabatic temperature change DTad of a Mn1.3Fe0.7P0.5Si0.55 Fe2P-type alloy was measured under different magnetic field-sweep rates from 0.93 Ts-1 to 2870 Ts-1. We find a field…
Extracting the Dynamic Magnetic Contrast in Time-Resolved X-ray Transmission Microscopy
T. Schaffers, T. Feggeler, S. Pile +11
Using a time-resolved detection scheme in scanning transmission X-ray microscopy (STXM) we measured element resolved ferromagnetic resonance (FMR) at microwave frequencies up to 10…
Element-specific visualization of dynamic magnetic coupling in a Co/Py bilayer microstructure
Thomas Feggeler, Ralf Meckenstock, Detlef Spoddig +8
We present the element-specific and time resolved visualization of uniform ferromagnetic resonance excitations of a Permalloy (Py) disk - Cobalt (Co) stripe bilayer microstructure.…
Unidirectional anisotropy in cubic FeGe with antisymmetric spin-spin-coupling
Nicolas Josten, Thomas Feggeler, Detlef Spoddig +8
We report strong unidirectional anisotropy in bulk polycrystalline B20 FeGe measured by ferromagnetic resonance spectroscopy. Bulk and micron-sized samples were produced and analyt…
Evaluation protocol for revealing magnonic contrast in STXM-FMR measurements
Benjamin Zingsem, Thomas Feggeler, Ralf Meckenstock +7
We present a statistically motivated method to extract magnonic contrast from STXM-FMR measurement with microwave frequencies of the order of \unit[10]{GHz}. With this method it is…
