Oscillatory behavior of the domain wall dynamics in a curved cylindrical magnetic nanowire (1710.04316v1)
Published 11 Oct 2017 in cond-mat.mes-hall
Abstract: Understanding the domain wall dynamics is an important issue in modern magnetism. Here we present results of domain wall displacement in curved cylindrical nanowires at a constant magnetic field. We show that the average velocity of a transverse domain wall increases with curvature. Contrary to what it is observed in stripes, in a curved wire the transverse domain wall oscillates along and rotates around the nanowire with the same frequency. These results open the possibility of new oscillation-based applications.
