Magnetic domain structure of magnetic shape memory alloy was observed using backscattered electron detector in scanning electron microscope and using Fresnel imaging in transmission electron microscope. The sample subjected to additional ion polishing allowed observation of the contrast associated with the magnetic structure of the material under conditions that exclude the use of Foucault or Fresnel transmission electron microscopy imaging. The additional research conducted using atomic force microscopy showed a significant relationship between the method of preparation and the magnetic shape memory alloy sample surface.
