| Summary: |
We present a study of the phase diagram for the multistep switching occurring in micrometer-sized ferromagnetic ring structures. The transition from the double to the triple switching is experimentally determined as a function of the geometrical parameters.We find that triple switching involving the vortexcore state is present only for a small range of geometrical parameters, since it requires a large film thickness, a large ring width, and a small inner diameter. The double switching prevails for other geometries. The phase boundary between the switching regimes can be explained by the results of micromagnetic simulations.
