Outline of Final Research Achievements

We have set our sights on the nanoscale imaging of spin current by nanoprobes. In the duration of this project, following tasks were performed. A nanoprobe measurement system using piezo positioners was developed. A technique for the measurement of surface voltage was established. Techniques for the fabrication of metal microwires on semiconductor wafers and the crosses of metal microwires were established. The current path imaging of ferromagnetic nanoparticulate film was performed using the developed nanoprobe system. A magnetic field source with high stability and low heat generation was developed for the nanoprobe measurements.
