Ordering tendency inside a surface segregation: application to Pt-Ni alloys

The composition profile inside a surface, showing segregation in a binary alloy, has been calculated from the simple nearest-neighbor-interaction model. For alloy systems with an ordering region an oscillation in composition is predicted even far away from the ordering region. This result is in gene...

Zusammenfassung:	The composition profile inside a surface, showing segregation in a binary alloy, has been calculated from the simple nearest-neighbor-interaction model. For alloy systems with an ordering region an oscillation in composition is predicted even far away from the ordering region. This result is in general agreement with experimental observation. 11 ref.--AA
