The potential of spin-polarized scanning tunneling microscopy and spectroscopy for the investigation of magnetism at the nanometer scale is demonstrated by focusing on magnetic domain walls. After reviewing different measurement modes it is shown that in addition to wall widths and positions the determination of their exact profiles provides further insight into the samples' magnetic properties.
