Magnetic response of FeRh to static and dynamic disorder
Benedikt Eggert, Alexander Schmeink, Johanna Lill +10
Changes of the magnetic and crystal structure on the microscopic scale in 40 nm FeRh thin films have been applied to investigate the phenomena of a disorder induced ferromagnetism…
Influence of hydrogenation on the vibrational density of states of magnetocaloric
Alexandra Terwey, Markus E. Gruner, Werner Keune +14
We report on the impact of magnetoelastic coupling on the magnetocaloric properties of LaFeSiH in terms of the vibrational density of states, which we dete…
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…
Effect of lattice excitations on transient near edge X-ray absorption spectroscopy
N. Rothenbach, M. E. Gruner, K. Ollefs +17
Time-dependent and constituent-specific spectral changes in soft near edge X-ray spectroscopy (XAS) of an [Fe/MgO] metal/insulator heterostructure upon laser excitation are ana…
Interface-related magnetic and vibrational properties in Fe/MgO heterostructures from nuclear resonant spectroscopy and first-principles calculations
Benedikt Eggert, Markus E. Gruner, Katharina Ollefs +11
We combine Fe Mössbauer spectroscopy and Fe nuclear resonant inelastic x-ray scattering (NRIXS) in nanoscale polycrystalline [bcc-Fe/MgO] multilayers with vari…
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.…
Microscopic non-equilibrium energy transfer dynamics in a photoexcited metal/insulator heterostructure
N. Rothenbach, M. E. Gruner, K. Ollefs +15
The element specificity of soft X-ray spectroscopy makes it an ideal tool for analyzing the microscopic origin of ultrafast dynamics induced by localized optical excitation in meta…
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…
