Abstract
AbstractThe x‐ray molybdenum M and nickel Lα1, 2 spectra were recorded for pure metals and several MoxNi100 − x alloys. The spectra for the pure metals were compared with the available theoretical density of states. The differences between the experimental and calculated data are presented after convolution with broadening functions. The modified p + f and d partial density of states (DOS) structure for molybdenum and nickel, respectively, is proposed. The changes in the DOS structure in alloys at the site of molybdenum and nickel atomas were estimated from experimental data. Broadening of the d band in nickel and the p + f band in molybdenum compared with the pure metal band was observed. These changes do not confirm the commonly used model of d‐band localization in metal alloys (e.g. in Cu70Zn30 alloy, which is also considered). A strong redistribution of valence band shape near the molybdenum atom after a change in crystal structure was also observed.
