| الوصف: | The atomic structure of a {110} surface of the ordered binary alloy FeRh is studied with quantitative low-energy electron diffraction. The structure of a surface with stoichiometric composition is found to be bulklike $(1\ifmmode\times\else\texttimes\fi{}1),$ but with a pronounced buckling, the Fe subplane being raised 0.15 \AA{} over the Rh subplane of the first layer, and the first interlayer spacing, measured from the Rh subplane of the first to the (bulklike and planar) second atomic layer, is contracted by 0.05 \AA{} (2.4%). Nonstoichiometric (probably Fe-poor) islands are found to have a reconstruction that may be labeled $3\ifmmode\times\else\texttimes\fi{}1$ when referred to the oblique unit mesh of FeRh{110}, but whose structure is unknown. A relation between specimen size and angular diffraction width is derived. |
