| Outline of Final Research Achievements |
Magneto-optical (MO) properties of magnetic nanostructures such as stacked nano-layers and 2-dimensional nano-arrays were investigated. MO cavity effect on magnetic stacked films indicated a giant MO Kerr rotation angle, and distinct MO responses were observed on the detection of hydrogen gas and on the measurement of chiral molecule (glucose). The MO cavity system is useful for chemical and biological sensing applications. Moreover, 2-dimensional arrays were formed on stacked films consisting of antiferromagnetically coupled (AFC) nano-layers. The AFC based on RKKY interaction presents magnetic or non-magnetic condition at the state of very short range compared with measurement optical wavelength. Pseudo magnetic dot arrays were formed on the AFC stacked films. I think that pseudo meta-materials with high-performance and multifunction are realized by binding of a plasmon near field and a magnetic spin alignment.

| Academic Significance and Societal Importance of the Research Achievements |
磁性積層膜における巨大磁気Kerr効果「磁気光学キャビティ効果」を利用したバイオ化学センサに関しては、国内学会でポスター講演賞を受賞するとともに、特許を取得して、製品化を目指した取り組みを民間企業と進めている。また、磁性ナノ粒子で見出した特異な物理現象「磁気光学位相反転」に関しては、局在プラズモン共鳴に起因することを明らかにし、国際論文がEditor's Picksに選出されるなど、国内外で高い注目を集める研究成果が得られた。さらに、磁性／非磁性状態が疑似的にアレンジ可能な磁性ナノ格子に関しては、新たな学術領域である「トポロジカルフォトニクス」への展開が期待できる研究成果であると考えている。
