Both topographical and corresponding surface potential images of an Fe-42Ni alloy sample surface have simultaneously been measured by SMM in a microscopical dimension. The Fe-42Ni sample was heat-treated in air in the range between 100°C and 400°C. The surface potential histogram obtained from each potential image pixels presents quantitative distribution of the surface potential, which is the difference in local work function of the sample increases with increase in oxidation temperature. A broad work function distribution resulting from various oxidation states was obtained from the sample oxidized at 200°C.
