Abstract

We investigated the magnetization process of Fe (110) film using the field dependence of magnetic Compton scattering and M\"ossbauer spectroscopy. From the magnetic Compton profiles, the spin and orbital magnetic moment specific magnetization versus magnetizing field curves were obtained. From the M\"ossbauer spectra, the angles between the magnetizing field and the magnetic moment were obtained. It was found that the magnetizing field dependence of the ratio between orbital moment and spin moment was related to the angles between the magnetizing field and the magnetic moment. We indicate that the magnetic field dependence of the orbital magnetic moment plays a role in the magnetization process.<br />本研究では磁気コンプトン散乱およびメスバーワー分光を用いてFe薄膜の磁化過程を詳細に調べた。磁気コンプトン散乱からスピン磁気モーメントと軌道磁気モーメントの磁化曲線を算出した。メスバーワースペクトルからは磁化と外部磁場のなす角の印加磁場依存性を調べた。これにより磁化曲線の振る舞いは磁化と外部磁場のなす角の変化と大きなかかわりがあることが分かった。
