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…
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…
A unified description of collective magnetic excitations
Benjamin W. Zingsem, Michael Winklhofer, Ralf Meckenstock +1
In this work, we define a set of analytic tools to describe the dynamic response of the magnetization to small perturbations, which can be used on its own or in combination with mi…
Specific Heat of Spin Excitations Measured by FerromagneticResonance
Benjamin W. Zingsem, Michael Winklhofer, Sabrina Masur +4
Using ferromagnetic-resonance spectroscopy (FMR), we investigate the anisotropic properties of epitaxial 3 nmPt/2 nmAg/10 nmFe/10 nmAg/GaAs(001) films in fully saturated meta-stabl…
Microwave soft x-ray microscopy for nanoscale magnetization dynamics in the 5-10 GHz frequency range
Stefano Bonetti, Roopali Kukreja, Zhao Chen +11
We present a scanning transmission x-ray microscopy setup combined with a novel microwave synchronization scheme in order to study high frequency magnetization dynamics at synchrot…
Dipole-dipole interaction in arrays of Fe/FeO core/shell nanocubes probed by ferromagnetic resonance
A. Sukhov, P. P. Horley, J. Berakdar +3
This paper represents a detailed theoretical study of the role of the longrange magnetic dipole-dipole interaction evidenced by the ferromagnetic resonance (FMR) spectra for the or…
