Research Abstract |
The main purpose of this project was to clarify couplings between lattice and quadrupole and magnetic orderings in rare earth antiferroquadrupolar ordering compounds through observations of thermal vibrations of nucleus and magnetic moments. For the observations, we proposed dichromatic neutron using two different wave lengths. We succeeded in upgrading a neutron powder diffractometer by this project. High resolution diffraction experiments with lower wave length, and wide -Q diffraction experiments with high wave length have been feasible on one diffractometer. Though the main experiments could not be performed because of the earthquake, feasibility of the wide-Q experiments with dichromatic beams has been confirmed. Moreover, by the upgrades, neutron holography experiments, and polarised neutronexperiments are realised on the powder diffractometer.
