| Outline of Final Research Achievements |
The purpose of the project is the observation of the crossed Andreev reflection in the novel structure in which the spin polarized current is injected efficiently into the superconductor/normal metal (S/N) bilayer with the very low Joule heating. As a result, the spin polarized component in the charge current could not be injected through the S/N interface. And also, it was experimentally shown that spin polarized electrons and Cooper pairs can co-exist in the normal metal layer. Moreover, by using the spin polarized current, it was realized that forming the superconducting gap at the S/N interface is observed. These results indicates that the S/N bilayer system have some advantage in the measurement in the superconductor-based hybrid nano-structure such as that for the crossed Andreev reflection measurement.
