はじめに
スピントロニクスは、電⼦スピンの有する不揮発性と⾼速操作を組み合わせることにより、情報を処理・記録する⾃由度として様々な機会を提供し続けています。強磁性⾦属はすでに、磁気ラ
ンダムアクセスメモリーや⾼感度磁気センサーとしてマイクロエレクトロニクスやスピントロニ
クスデバイスに組み込まれています。また半導体においては、スピンのコヒーレンス時間が⾮常に⻑いため量⼦スピン操作の実現が可能であるとともに、⻑いスピン拡散⻑を活⽤したスピン輸
送と操作も実現されています。さらに、スピンの⾃由度を電気的に制御することで、ロジックやメ
モリ機能を統合することが可能になり、多様な材料において普遍的な概念や機能を⽣み出すプラットフォームになっていると⾔えます。このようなスピンに関わる様々な現象やデバイス応⽤を議論する場を国内で継続的に提供してきたのが PASPS であり、最新結果や未発表のデータについても、学⽣を含む若⼿研究者やシニアな研究者が多⾓的な観点で議論を⾏いインキュベートできる環境を育んできました。
近年スピントロニクスのみならずトポロジカルエレクトロニクス、バレートロニクスなど極めて広い分野においてスピン物性は重要な役割を果たしています。⼀⽅で、分野の垣根を越えて深い
物理的な理解や若⼿研究者のネットワークを形成する場が、逆に分野が細分化されはじめていることから多く⾒受けられておりません。そのような中で、本 PASPS では、スピンに限らず様々な分野を取り込んで、原理原則に戻り議論を⾏うことでお互いが分野を異にしても共通理解を促進
し、基礎科学からデバイス応⽤に⾄るまで様々な課題に対する研究の⽅向性を刺激し、研究者同⼠のネットワークを広げることを⽬的としています。27 回⽬を迎え、その間に研究環境やトレンドが⼤きく変化している中でも、切磋琢磨しながら研究を発展させる研究者同⼠のつながりと成果発表の場となれば幸いです。

PASPS について
PASPS とは本研究会は、ʻʻPhysics and Applications of Spin-related Phenomena in Semiconductorsʼʼ (半導体におけるスピン⼯学の基礎と応⽤) の頭⽂字を取って “PASPS” と称し、1995 年に東北⼤学電気通信研究所共同プロジェクト研究として開催されて以来、ほぼ毎年回を重ね、今回で 27 回⽬を迎えました。この間、研究会の対象とする分野は、当初の磁性半導体、半導体ナノ構造など半導体を中⼼としたものから、最近では、⾦属薄膜、原⼦層物質、トポロジカル絶縁体をはじめとして、広く固体⼀般におけるスピンに関連する物性、およびその応⽤に広げて参りました。この研究会
では、スピントロニクスに関連する研究者が⼀堂に会し、未発表データを含む最新の研究成果を発表、ご議論いただくことにより、当該分野の研究の進展、情報交換および研究者間の親睦を図ることを⽬的としています。

対象とする分野
磁性半導体、⾮磁性半導体のナノ構造、磁性体と半導体との複合構造、磁性体や超伝導体、有機材料を包含した融合・複合構造、などの作製およびスピンに関連する現象、さらにグラフェンをはじめとした低次元物質、トポロジカル物質、スピン輸送・スピン依存伝導、電⼦・核スピン操
作・検出、スピン関連現象のデバイス応⽤、等を対象とします。加えて、最近の研究動向を踏まえ、新しい技術や視点を意識した基礎・応⽤展開、など多岐にわたる研究発表も広く取り扱います。
