Outline of Final Research Achievements |
We have studied some Lanthanide and Actinide compounds by mainly probing nuclear quadrupole interaction and have shown the usefulness of this technique. For example, for URu2Si2, we obtained information on the valence of U ion and local structural symmetry. For SmB6, we succeeded in performing the measurement of nuclear magnetic resonance (NMR) at an extremely high pressure of 6GPa, to investigate the pressure dependence of Sm valence. We also carried out the measurement of nuclear quadrupole resonance (NQR) below 100mK and observed a crossover phenomenon between localized and itinerant states around an extremely low temperature of 200mK. Moreover, from the measurements of high-field NMR and zero-field NMR/NQR, important information on the ordered structures of Eu valence and magnetic moments were obtained.
