High resolution magnetic force microscopy of domain wall fine structures (invited)

Magnetic force microscope (MFM) images of various domain wall structures will be discussed. The systems studied in this work include single crystals of magnetite (Fe/sub 3/O/sub 4/) and a 0.5 /spl mu/m single crystal iron (Fe) film. In general, the observed structures can be explained in terms of a bulk Bloch wall terminated at the surface by a Neel cap. A model of the MFM response to such a structure has been fitted to the measured response, demonstrating the utility of MFM data for testing micromagnetic models. >
