Outline of Final Research Achievements

When the system size is decreased below the characteristic length such as the correlation length, qualitatively different behavior associated with the reduced dimensionality can be observed.
We study ferromagnetic transitions of paramagnetic Pd caused by downsizing via transport measurements. A clear magnetoresistance effect with hysteresis is observed in Pd nanometer-sized constriction below about 30 nanometer. In Ni atomic-scale contact, we observe a Fano resonance with a zero-bias anomaly, likely due to the Kondo effect, which persists in large size constrictions with nearly 50-atom configurations. The results suggest that the Kondo effect and ferromagnetism could coexist in the ferromagnetic nanoconstrictions.
We study H atom absorption and diffusion in Pd nano-contacts immersed in liquid hydrogen using inelastic electron spectroscopy. H absorption develops by applying bias voltage 30-50 mV, which can be understood by quantum tunneling of H atom.
