Description:
Author(s): R. Badea, E. Haber, and J. Berezovsky Fast manipulation of nanoscale magnetic textures, such as vortices and skyrmions, underlies devices proposed for next-generation magnetic memory, logic, and sensing. Understanding the switching processes in these structures requires a probe with both nanometer spatial resolution and nanosecond time resolution. This study combines time-resolved magneto-optical microscopy and single-spin magnetometry to unveil the switching of a magnetic vortex between pinning sites, in response to a short magnetic field pulse. The complex dependence of switching probability on pulse duration is explained, revealing a path toward the fast, reliable control required for future nanomagnetic technology. [Phys. Rev.
