Pertubed Angular Correlation Study of Kondo Alloys, La_<1-x>Y_x(^<140>Ce)
スポンサーリンク
概要
- 論文の詳細を見る
Perturbed angular correlation technique has been utilized to observe the fluctuation of the hyperfine field at ^<140>Ce nuclei in La_<1-x>Y_x alloys from 1.7 K to 300 K at vanishing concentration of the Ce impurity without applying an external magnetic field. The fluctuation is associated with the localized 4f electron spin of Ce atoms. The temperature dependence of the fluctuation time deviates from the 1/T dependence of Korringa relaxation. The deviation becomes more prominent as the Y concentration increases. The phenomenon has been interpreted in terms of the Kondo effect. The Kondo temperatures were deduced from the temperature dependence of the fluctuation time. The relaxation of ^<140>Ce nuclear spin is also discussed.
