By exploiting different pumping field configurations in ferromagnetic resonance (FMR) experiments, four new modes are found in the FMR excitation spectrum for the magnetic stripe domain structure in epitaxial Co(0001) thin films. These modes provide evidence for the two-dimensional domain wall profile consisting of Bloch wall sections in the film center as well as large flux closure caps at the film surface.
