| Outline of Final Research Achievements |
Unique technique for simultaneous measurements of neutron diffraction and electrical resistivity under high pressure and low temperature have been developed to investigate novel behavior in strongly correlated 4f electron systems from the point of view of the relation between structure, magnetism and electrical conductivity. For resistivity measurement, the anodic oxide coating was adopted as the insulation layer of the aluminum gasket used in the hybrid-anvil device for neutron diffraction. In the feasibility tests of the coated gaskets, maximum pressure of about 5.5 GPa was generated without electrical breakdown of the coating or disconnection of Au leads. By using above technique, it was revealed that metal-insulator transition in filled skutterudite compound PrFe4P12 under high pressure is closely related to pressure-induced magnetic order.
