FIG. 1.

(a) Calculated spin distribution of a magnetic vortex in a diameter, thick circular dot of permalloy. To represent the effects of field cooling at remanence, a pinning field in the shape of a vortex, including the core, is imposed. (b) Oscillations of the vortex magnetization as a function of time with and without a local pinning field of after removing a perturbation field of .
