abstract = {The field dependent magnetization of three mutually
touching permalloy rings were investigated by means of the
magneto-optical Kerr effect, magnetic force microscopy, and
micromagnetic simulations. Each ring has a width of 0.2-1.8
mu m, an outer diameter of 4 mu m, and a thickness of 17 nm.
Decreasing an applied magnetic field from saturation leads
to the nucleation and annihilation of magnetic vortices,
leaving at least one ring in a magnetically frustrated
state. The properties of the magnetization reversal strongly
depend on the ring width and on the direction of the applied
field. Multiple complex reversal paths with vortexlike
magnetization configurations are found.},
