    Localized micromagnetic perturbation of domain walls in magnetite using a magnetic force microscope
    (Applied Physics Letters (American Institute of Physics), 1996) Foss, Sheryl; Proksch, Roger; Dahlberg, E.D.; Moskowitz, Bruce; Walsh, B.
    Magnetic force microscope(MFM) profiles of domain walls (DWs) in magnetite were measured using commercially available MFM tips. Opposite polarity profiles of a single DW segment were obtained by magnetizing the MFM tip in opposite directions perpendicular to the sample surface. During a measurement, the field of the tip locally magnetized the DW, resulting in a more attractive tip‐sample interaction. The difference between opposite polarity DW profiles provided a qualitative measurement of the reversible changes in DW structure due to the localized field of the MFM tip.
