Abstract

Magnetic force microscopy (MFM) is used for investigation of magnetic structure in steels Fe - 28 Mn - 8.5 Al - 1C - 1.4Si under the different regimes of isotermic aging. A theoretical model for the MFM image of such a structure is developed. Also the calculation method of the van der Waals forces is considered which may be used for the interpretation of the topography measurements. The utility of MFM data is demonstrated for testing of micromagnetic structure of steels and conditions are formulated which should be fulfilled to look into its details.
