** Current induced dynamics of Domain Wall [#bedd3bbd]
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.~
