| Research Abstract |
We have studied Yb-, Sm-, Eu-, and U-based heavy fermion compounds mainly by Nuclear Magnetic Resonance(NMR) measurements, so that important information about local symmetries and magnetic field effects on these compounds have been obtained. Especially, i) We have clarified the mechanism of strong field effects in YbCo_2 Zn_<20>. ii) In order to study the phase transition(so called "hidden order") at 17.5 K in URu_2 Si_2, we have introduced a new method for investigating local structural symmetries via nuclear quadrupole interactions. iii) For EuPtP, we have succeeded in assigning how symmetries of the system change at the phase transitions accompanied by Eu valence changes.
