Study of interdiffused layers in the surface and interfaces of multilayers by total-reflection soft-X-ray fluorescence spectroscopy

Imazono, Takashi; Yanagihara, Mihiro*

Photon Factory News, 22(3), p.18 - 22, 2004/11

Using soft-X-ray fluorescence spectroscopy with photon incidence at a critical angle of total reflection, it was made clear that SiO$$_2$$ existed within a depth of a few nanometers from the surface of Fe/Si multilayers. It was generated by oxidation of the interdiffused Fe$$_3$$Si layer nearest to the topmost Fe layer. Consequently, the Fe$$_3$$Si layer was found to decrease in thickness. This result suggests that the total-reflection soft-X-ray fluorescence spectroscopy is fairly useful to analyze the chemical state of elements to a depth of a few nanometers from the surface.

Diffusion of cerium in uranium-zirconium solid solutions

Ogata, Takanari*; Akabori, Mitsuo; Ito, Akinori

Materials Transactions, 44(1), p.47 - 52, 2003/10

Diffusion behavior of Ce in U-Zr alloys was studied from the interdiffusion with diffusion couples. The diffusion coefficients of Ce in the U-Zr solid solutions ($$gamma$$U, $$beta$$Zr) were estimated to be 2$$times$$10$$^{-13}$$ and 6$$times$$10$$^{-14}$$m$$^{2}$$/s at 1023 and 1123 K, respectively. The result also indicated that Ce does not significant influence on interdiffusion in the U-Zr solid solutions.
