Abstract
Magnetic force microscopy (MFM) is used to investigate the surface magnetic structure of steels Fe-28Mn-8.5Al-1C-1.4Si under the different regimes of isothermal aging. A theoretical model for the MFM imaging of such structure s is developed. Calculation of van der Waals forces is performed in order t o interpret the topography images. The lateral resolution in terms of the m agnetic field dependence on the surface coordinates is investigated. Finall y, conditions that should be fulfilled for a good imaging of the samples ar e formulated.
