Non-linear radial spinwave modes in thin magnetic disks
M. Helsen, A. Gangwar, J. De Clercq +2
We present an experimental investigation of radial spin-wave modes in magnetic nano-disks with a vortex ground state. The spin-wave amplitude was measured using a frequency-resolve…
Magneto-Optical Spectrum Analyzer
Mathias Helsen, Ajay Gangwar, Arne Vansteenkiste +1
We present a method for the investigation of gigahertz magnetization dynamics of single magnetic nano elements. By combining a frequency domain approach with a micro focus Kerr eff…
Unidirectional sub-100 ps magnetic vortex core reversal
Matthias Noske, Ajay Gangwar, Hermann Stoll +8
The magnetic vortex structure, an important ground state configuration in micron and sub-micron sized ferromagnetic thin film platelets, is characterized by a curling in-plane magn…
