Outline of Final Research Achievements

In the present study, we investigated the surface magnetic ordering of a molecular oxygen layer adsorbed on Ag(111) by using a spin-polarized atomic hydrogen beam. We optimized the flux of the molecular hydrogen beam and created positioning devices of the magnets and mass spectrometer. We also measured the velocity of the molecular hydrogen beam and angular distributions of the scattered molecular hydrogen beam from surfaces by resonance-enhanced multi-photon ionization. Although we could not measure the surface magnetic ordering due to a lower flux of the atomic hydrogen beam, the development of the necessary parts was accomplished and we think that the surface magnetic ordering can be investigated if the flux of the atomic hydrogen beam is increased further.
