Reversal of Flux Closure States in Cobalt Nanoparticle Rings With Coaxial Magnetic Pulses
Date of this Version11-18-2008
This document has been peer-reviewed.
Bistable flux closure (FC) states in Co nanoparticle rings can be switched reversibly by applying a coaxial magnetic field (H-z). The FC switching phenomena can be reproduced by micromagnetics simulations, which also reveal novel magnetic states at intermediate applied field strengths.
