Abstract
A quantitative analysis of the surface composition of the Heusler alloy NiM
nSb has been undertaken using angle-resolved x-ray photoemission spectrosco
py and the surface composition characterized. With sufficient annealing cyc
les, the stoichiometric surface evolves to a surface that is manganese rich
. This indicates that the surface enthalpy is different from the bulk for t
he Heusler alloy NiMnSb. (C) 2000 American Institute of Physics.[S0003-6951
