Magnetic microstructures of NiFe/Cu/NiFe tri-layer films were observed by means of Lorentz microscopy. The in situ observations in the magnetic field were carried out by simply tilting the films inside a transmission electron microscope. Using the domain wall contrast and the ripple contrast as a guide, the magnetic microstructures of adjacent NiFe layers could be analysed separately. The change of the magnetic microstructure corresponded to the magnetization curve and the suitability of the present method was confirmed. The angle distribution of magnetic moments belonging to adjacent NiFe layers was determined in each Lorentz image, and it was expected that the magnetoresistance ratio changed place by place in the film.
