Abstract: Antivortices are fundamental magnetic structures found alongside vortices in soft magnetic extended films and in patterned elements above a few micrometers in size. While the dynamic behavior of vortices has been the object of numerous studies, the magnetization dynamics of antivortices has not been studied as thoroughly. Using micromagnetic simulations, we investigate the dynamics of a single isolated antivortex in response to subnanosecond external field pulses. We find that these pulses can trigger the reversal of the antivortex core. This reversal mechanism is complementary to the one recently found in the vortex core switch. We also investigate the stability of the switching process in the isolated antivortex structure.
