Abstract

Using time-of-flight mass spectrometry, we observed the mass abundance spectra of iron-oxide clusters produced in a reactive laser vaporization cluster source. Fe13O8 is much more abundant than the other oxide clusters. An ab initio calculation proposed the following structure for Fe13O8: thirteen iron atoms form one atom-centered tetragonally-distorted fcc core and the eight oxygen atoms adsorb on the threefold sites of the core. There is a trend of stable iron-oxide clusters, FeO2(Fe2O)cursive Greek chi with cursive Greek chi < 9, during preparation at low oxygen flow rates.
