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…
Template-Assisted Direct Growth of 1Td/in Bit Patterned Media
En Yang, Zuwei Liu, Hitesh Arora +8
We present a method for growing bit patterned magnetic recording media using directed growth of sputtered granular perpendicular magnetic recording media. The grain nucleation is t…
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…
