Outline of Final Research Achievements

Spin-polarized scanning tunneling microscopy and tip magnetization control technique were established to enable spin analysis with atomic-level spatial resolution, and the scanning tunneling potentiometry was successfully operates in an ultrahigh vacuum and at low temperatures, and the electrical resistance associated to individual defects on the surface was measured. By introducing microwaves into the ultra-high vacuum and low-temperature STM apparatus, we also succeeded in capturing the change in magnetic contrast with and without microwave irradiation, suggesting the possibility of local detection of ferromagnetic resonance.

Academic Significance and Societal Importance of the Research Achievements

原子一つ一つのスピン・磁化情報や、表面での単一の欠陥構造に起因する電気抵抗を微視的に検出することはこれまでに無い技術であり、その観測は学術的意義が高いと言える。また本研究でその可能性が示唆されたナノサイズ磁性アイランド構造における強磁性共鳴の検出も、その磁気的なダイナミクスを明らかにする上で重要であり、これまでのスピン偏極走査トンネル顕微鏡による静的なスピン・磁化情報と合わせて、強力な磁気分析ツールとなりうる可能性を秘めている。
