1.硫酸銅水溶液において、偏光を利用したポンプ-プローブ法を用いて、銅イオンの基底状態の光誘起磁化を生成し、ピコ秒領域の磁化の減衰を観測した。磁場を加えるとあるいは濃度を薄めると緩和時間が長くなることがわかった。この結果は、磁化の減衰が銅イオン間の磁気的双極子相互作用によるスピン交差緩和であることを示唆している。また、横磁場中におけるピコ秒領域の磁化の才差運動を観測し、フーリエスペクトルの尖鋭化から溶液中の錯体分子の運動について議論した。2.室温のAl_2O_3結晶中Cr^<3+>イオン(ルビー)において、光誘起磁化を生成・検出する実験を行った。光学遷移の選択則を利用して円偏光のポンプ光で基底状態に磁化を生成し、直線偏光プローブの偏光の変化として検出した。ナノ秒領域の磁化の緩和と横磁場中におけるピコ秒領域の磁化の才差運動が観測された。3.ルビジウム原子気体D_1線の基底状態にポンプ-プローブ法を適用し、光誘起磁化の生成、磁気円偏光二色性を用いた磁化の検出、磁気円偏光複屈折を用いた磁化の検出、自由誘導減衰の観測、及び光誘起スピンエコーの観測を行った。その結果、スピンの光制御に必要な磁化の光学的生成、光学的検出、及び位相の制御が実現できることがわかった。4.共鳴光励起の場合と非共鳴光励起の場合に対する光誘起スピンエコーについて、4準位系を用いたベクトルモデルを考察した。本研究で観測した光誘起スピンエコーは共鳴光励起型であり、任意軸周りのスピン回転を実現するためには吸収の影響が残り、まだ不十分である。任意の軸周りのスピン回転は、ポンプ光とプローブ光の周波数を変えたポンプ-プローブ法を用いた非共鳴光励起型の光誘起スピンエコー法で実現できると期待される。スピン回転の光制御が実現すれば量子幾何学位相の観測が可能になると思われる。

1. Sulfuric acid aqueous solution is used to generate magnetization, polarizer and polarizer are used to generate magnetization in the base state of the base state of the sulfuric acid aqueous solution, the polarizing method is used to generate the magnetization of the base state light, and the field of magnetization in the second domain. The magnetic field increases the temperature, the temperature and the time. The results of the experiment, the two-pair interaction of the magnetization, the decay and the magnetization of the magnetic field show that the two-pole interaction between the magnetic field and the magnetic field is instigated by the two-pole interaction of the magnetic field. In the field of magnetic field and transverse magnetic field, the difference of magnetization in the field of magnetization is different from that of the wrong body and molecules in the solution. two。 In the room temperature temperature Al_2O_3 crystal, the CR^ & lt;3+> temperature is different from that of the light-induced magnetization, and the output temperature is different. Optical shift Select to use polarization to generate magnetization, straight polarization to polarize light, to generate magnetization. In the field of magnetization and transverse magnetic field, there is a difference in the field of magnetization in seconds. 3.
