Suppression of Magnetization Ringing After Domain Wall Collision Studied by Micromagnetic Simulation
Journal of Magnetics, Volume 13, Number 4, 31 Dec 2008, Pages 120-123
Abstract
Magnetization ringing following domain wall collision on a ferromagnetic nanowire has been investigated by micromagnetic simulation. Suppressed magnetization ringing is observed with the introduction of a small ribbon to the nanowire. Magnetization ringing has been analyzed in a frequency space by a fast Fourier transform. With the introduction of a small ribbon and/or taping of the wire, the amplitude of ringing is reduced with a shifted frequency peak.
