What is Development of a quantitative energy filtering TEM method to study a reactive NiO/80Ni20Fe interface about?
Energy filtering TEM (EFTEM) has been performed on an annealed NiO/ 80 Ni 20 Fe interface. Chemical maps have been calculated using the three-window technique on the O-K, Fe-L 23 and Ni-L 23 edges. In this paper we show that relative quantification can be made using reference areas on the images taken from part to part of the interface in wellknown composition areas. Partial cross-section ratios s Ni ð20 eVÞ=s O ð20 eVÞ and s Ni ð20 eVÞ=s Fe ð20 eVÞ have been then measured and used to extract the chemical composition of the reactive NiO/ 80 Ni 20 Fe interface. Fe, Ni and O composition profiles across the interface have been obtained showing the diffusion process which has occurred during annealing. The reliability of the EFTEM measurements has been checked by EEL spectroscopy on the same sample as well as on a reference geological oxide sample (Trevorit: NiFe 2 O 4 ). The partial cross-section ratios obtained with the two methods (EFTEM and EELS) are in good agreement.
