Abstract

We have deposited Mn on the (110) surface of Ni and discover ordering into a (formula presented) superstructure for coverages of 0.35–0.5 monolayer Mn. (formula presented) photoemission spectra show distinct satellite structures which disappear for higher Mn coverage. Calculations using configuration-interaction theory including multiplet effects on a model cluster representing the local geometry of a surface alloy identify the features as correlation satellites and give model parameters as follows: charge-transfer energy Δ=1 eV, Coulomb energy (formula presented) and transfer integral (formula presented) A detailed comparison to the case of (formula presented) Mn/Cu(100) leads to the conclusion that (formula presented) Mn/Ni(110) is a new magnetic surface alloy.
