| Abstract: | Segregation of chromium to the surface of a Fe72Cr28(110) crystal has been characterized by X-ray photoelectron spectroscopy. Using XPS core level emissions with different electron mean free paths, the profile of chromium concentration from the surface to the bulk has been constructed and compared to results from Ar+ ion sputtering experiments. |
