概要: Departmental Bulletin Paper<br />Eight Fe-films with a thickness different from one another have been prepared by deposi … ted on clean Sm surfaces with accuracy of 0.1 nm (Fe(d nm)/Sm(10.0nm)(d＝0.3,0.5,0.7,1.0,1.5,2.0,5.0,10.0)),and the\nFe 2p3/2XPS spectra of the films have been,in situ,measured at about 8K and room temperature. A shift in the binding energy position of the Fe 2p3/2lines is found to depend on the film thickness and the temperature.\nAt both temperatures,the shift from a peak position of the Fe 2p3/2line in Fe(10.0nm)/Sm(10.0nm)is hardly found in the range of～1-10 nm,whereas it increases monotonously to the low binding energy side as the film\nthickness decreases in the range of 0.1-～1nm. The value of the shift at about 8K seems to be larger than that at room temperature slightly in the range of 0.1-～1nm. Comparing with the case of Sm(d nm)/Fe(10.0nm)\nfrom Chihiro IIJIMA and Makoto OKUSAWA (2010),this suggests that a change in an electronic state takes place in the vicinity of a Fe-Sm interface,and that a charge density on the Fe side becomes large and that on\nthe Sm side small. Detailed discussion will be presented elsewher. 続きを見る
