DESCRIPTION:Magnetic vortices occur in soft magnetic nanodisks with suitabl
 e dimensions. The spin structure curls in the plane around the center wher
 e it points out-of-plane either up or down\, defining the polarization P =
  ±1. Thus\, the vortex core represents a binary digit that can be used fo
 r magnetic storage devices. Ferromagnetic resonance spectroscopy is used t
 o investigate the high-frequency spectra of two stacked vortices depending
  on the relative polarizations. In this work\, it is shown that magnetic f
 ield bursts with frequencies in the Gigahertz range can be used to control
  the polarization on a sub-nanosecond time scale. The demonstrated writing
  times are more than two magnitudes faster compared to settling times achi
 eved with the gyrotropic mode. Furthermore\, polarization dependent spin-w
 ave modes that lead to a selective spin-wave mediated vortex core reversal
  are imaged by scanning transmission X-ray microscopy.\nVortragende(r): Be
