Abstract

Several MBE (molecular beam epitaxy) thin-film and single-crystalline surfaces of magnetite have been investigated by means of the low-energy ion scattering (LEIS) technique. Distinct anomalies in the temperature dependence of the scattered ion yield, R+(T), were observed in the metal-insulator phase transition region. The characteristic of the R+(T) curves indicated a complex interplay between the dominant Auger neutralization and re-ionization of neutralized particles in the outgoing path.
