Persistent excitation of spin waves for kπ-state skyrmions

In this study, we investigated the micromagnetic dynamics of k π -state skyrmions in a magnetic nanodot under a circular spin-polarized current and found an excited spin wave that can propagate persistently along the direction of the radius toward the center. This dynamic process is associated with...
