Electronic current with the spin polarization drive the precession motion of the magnetization.
In the case of domain walls, the precession corresponds to the following Bloch-Neel oscillation
and is expected to be available as a microwave source.
- A current driven Bloch-Neel oscillation of a pinning domain wall in a confinment region.
- Breathing mode of domain wall which induces microwave voltage signal.
