‚SDDevelopment of Spin-Polarized Scanning Tunneling Microscopy

@Scanning probe microscope (SPM) is a powerful tool to analyze and manipulate the nanostructures. In Yamaguchi lab., development of a new SPM system has been tried to get some information concerning surface spin structures and magnetic domains with an atomic scale. Recently, spin-dependent tunneling signal has been successfully detected by a newly developed STM system using the semiconductor microtip.
