| Research Abstract |
The purpose of this research is to clarify the physical properties related to multipoles of f electrons in strongly correlated electron systems with high symmetry mainly by neutron scattering experiments. I have tried to do inelastic neutron scattering experiments at very low temperatures on (Ce,La)B^6 which is a typical system showing multipole order. However they have not been successful so far unfortunately because of technical troubles of cooling the sample, but, I could get the preliminary data about the dynamical properties of 4f electrons in the paramagnetic phase of this system. In the typical strongly correlated 5f electron system U(Ru,Rh)^2Si^2 which is considered to be related to multipoles of 5f electrons, on the other hand, the magnetic structure of the mysterious field-induced phase was determined by high-field neutron diffraction.
