Outline of Final Research Achievements

By using several complementary experimental probes, we have elucidated the electronic properties of iron-based ladder compounds. It is found that the 3d electrons of Fr irons exhibit a variety of magnetic and orbital orders due to the low dimensionality, multi-orbital nature, and strongly correlated electron effects. Fluctuations of the stripe-type magnetic order/ferro-type orbital order is responsible for the formation of superconductivity, while block-type magnetic order/propeller- type orbital order shows the multiferroic phenomena.

Academic Significance and Societal Importance of the Research Achievements

超伝導やマルチフェロイクスを示す材料は、次世代エレクトロニスで使用されるデバイスの基盤材料として有望である。本研究を通して、超伝導やマルチフェロイクスが発現する微視的機構が電子論的に解明されたことは意義深く、将来、より高温で動作するデバイス・より高い機能を有するデバイスを作成することに繋がる。
