Spin polarization and structure of thin iron oxide layers prepared by oxidation of Fe(1 1 0)

The structure and magnetism of thin iron oxide layers formed on a Fe(1 1 0) single crystal surface are investigated by Auger electron spectroscopy, ion beam triangulation, and spin polarized secondary electron emission. The formation of a FeO(1 1 1)-like film on top of the metal substrate is observe...

Description
Summary:The structure and magnetism of thin iron oxide layers formed on a Fe(1 1 0) single crystal surface are investigated by Auger electron spectroscopy, ion beam triangulation, and spin polarized secondary electron emission. The formation of a FeO(1 1 1)-like film on top of the metal substrate is observed for oxidation at elevated temperatures. Additional oxygen exposure at room temperature is suggested to lead to a gradual conversion to Fe 3O 4.
