Outline of Research at the Start

磁性体デバイスの集積化に伴い、磁性体のナノサイズ効果を無視することができなくなりつつある。したがって、ナノサイズ磁性体の状態を検出することが重要となる。スピン分解走査トンネル顕微鏡は、磁化状態をナノスケールで検出できる有用な手法であるが、静的な情報しか検出することができない。そこで高周波電磁場による強磁性共鳴に着目した。強磁性共鳴を引き起こさせると短時間磁化状態を制御することができ、結果として動的特性を検出することができる。本研究では、強磁性共鳴を組み合わせることで磁性体の動的な特性をナノスケールで検出することを目的としている。

Outline of Final Research Achievements

The purposes of this research are development of the system to detect nanoscale ferromagnetic resonance using scanning tunneling microscopy (STM) and investigation of dynamic properties of nanosized magnetic materials. We developed the STM system, which can apply very high frequency (about 16GHz) electric field. We also successfully fabricated monolayer chromium bromide, which shows a ferromagnetic order. In addition, to perform high sensitive measurements, we focus on scanning tunneling potentiometry (STP) methods. We developed low temperature STP system successfully.

Academic Significance and Societal Importance of the Research Achievements

本研究を通して、単原子層磁性体薄膜を作製した。これまで、超伝導体や半導体など、様々な単原子層薄膜が作製されてきたが、磁性体の例は多くない。単原子層磁性薄膜は、本研究で対象としたナノサイズ磁性体としてだけでなく、界面現象の研究にも応用可能であり、大きな意義がある。また、本研究を通して開発された極低温走査トンネルポテンショメトリ法はナノメートルスケールかつ高感度での化学ポテンシャルを測定できるため、共鳴によって誘起されるスピンポテンシャル検出への応用が期待される。
