| Outline of Final Research Achievements |
Hyperfine fields at impurity of rare-earth elements in ferromagnetic hosts are important for the verification of the first principle calculations. Once a hyperfine field is determined in a sufficient accuracy, this field can be used for the determination of magnetic moments of intermediate states of nuclei. In this study, the measurement of the hyperfine field of Pm in Fe was performed. Behavior of defects introduced through the implantation process of impurities was also studied by the perturbed angular correlation measurement of Ce-140 in Fe. The possibility of the perturbed angular correlation measurement using the gamma-rays that are not directly interpose the intermediate state is investigated for the magnetic moment measurement. Improvements on the measurement system is performed.
