Dynamics of polarization vortices revealed in a ferroelectric material

Vortices of electrical polarization have been observed to vibrate at extremely high frequencies in a material called a ferroelectric. Such motion could be directly controlled by electric fields for ultrafast data processing. Direct observation of vibrations of vortices of electrical polarization.
