| Research Abstract |
Spin-polarized metastable-induced electron spectroscopy (MIES) has been developed to analyze electronic and magnetic properties of topmost surface layers of magnetic materials. The MIES has been applied to the analysis of surface oxidation/reduction processes at a Ni (110) surface and also of the electronic structure of NiO surfaces. The rate of reduction reaction by hydrogen depends on the local atomic structure of oxidized surfaces. MIES spectra reflected electron correlations of the Ni d bands. Initial processes of magnetic thin film growth on semiconductor surfaces have been investigated by Auger and photoelectron spectroscopies.
