Magnetic microstructure and magnetoresistance (MR) were simultaneously investigated for an Ni0.8 Fe0.2 film with dimensions of 2mm× 100μ m× 35nm. An in-situ experiment in a magnetic field was carried out by simply tilting the film inside a transmission electron microscope. Using the ripple contrast of Lorentz images as a guide, the inhomogeneous distribution of the magnetization was investigated. Comparing the result obtained by Lorentz microscopy with the magnetoresistance of the film, we quantitatively investigated the distribution of the MR-curve within the film. The influence of the film edge on the MR-curve extended to 20μ m from the edge. The feasibility of simultaneous in-situ experiments involving Lorentz microscopy and magnetoresistance measurements was confirmed.
