- Descrição
- Magnetic force microscopy is used to investigate the magnetic structure of steels Fe–28Mn–8.5Al-1C-1.4Si under different regimes of isothermal aging. A theoretical model for the magnetic force microscopy imaging of such structures is developed. Calculations of van der Waals forces were performed in order to interpret the topography images. The lateral resolution in terms of the magnetic field dependence on the surface coordinates is also investigated. Conditions that should be fulfilled for a good imaging of the samples are also formulated.
