Outline of Final Research Achievements

A new scanning probe technique, Scanning Electronic-Magnetic Effect Microscopy (SEMEM), has been studied by combining both scanning probe techniques such as Scanning Gate Microscopy (SGM) and Magnetic Force Microscopy (MFM) in order to detect a localized spin induced by electric field. By sweeping the probe voltage or the source-drain voltage with fixing the tip position on the sample surface, a new probing technique namely a Scanning Gate Spectroscopy (SGS) has been realized in this study. In addition, using a ferromagnetic tip, the technique can be expected to detect a localized spin moment.
