Direct non-intrusive imaging and magnetoresistance measurements have been employed to investigate the head-tohead domain walls occurring in micrometre-sized NiFe and Co rings. In wide rings vortex head-to-head domain walls are found to be present. These vortex head-to-head walls are repelled by cons
