| Abstract |
次世代垂直媒体のマイクロ波アシスト磁気記録の実現に向けて, 電場結合型スピン注入素子の開発に必要な要素技術について研究した。まず, 横型スピンバルブ素子を用いて, スピン流によるスピントルクをセンス電流なしで高感度測定することに成功した。また, スピンポンピング由来の直流・交流混合スピン流により強磁性薄膜パターンの磁化反転磁場が減少することを明らかにした。さらに, 櫛型電極と圧電基板を用いて電場結合FMR誘引実験を行ない, 高周波化に必要な素子設計を調べた。
In order to realize a microwave-assisted magnetic recording in next generation perpendicular medium, we studied some essential technologies needed for developing an electric field coupled spin injector. First, we succeeded to measure a spin transfer torque due to a spin current precisely by using a lateral spin valve structure. Then, it was demonstrated that the magnetization reversal in patterned ferromagnetic thin films could be assisted by a spin current owing to a spin pumping. Furthermore, we examined a circuit design for an electric field coupled excitation of FMR by using a test device composed of interdigital transducers on a piezoelectric substrate.
