Co-Nanowires

by Hermann Forster


domain wall velocity
vortex wall
Domain wall veloctiy for different diameters d of the Co-nanowire. The velocity depends on the domain wall structure. The simulations were made for a damping constant of one. This animation shows the motion of a vortex domain wall. The diameter is 40 nm. The external field is 200 kA/m. The colors represent the magnetization component parallel to the long axis.
