• Magnetic microstructure and magnetoresistance (MR) were simultaneously investigated for an Ni_<0.8>Fe_<0.2> film with dimensions of 2 mm × 100 μm × 35 nm. 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 20 μm from the edge. The feasibility of simultaneous in-situ experiments involving Lorentz microscopy and magnetoresistance measurements was confirmed.
