Research Abstract

Single crystals of actinide layered compounds ThCuPO and UCuPO have been successfully grown by the chemical transport method. Using these single crystals, the crystal structures and chemical compositions have been evaluated. The measurements of resistivity, specific heat, and magnetization for UCuPO have revealed that the strong magnetic anisotropy causes from the localized 5f electrons of uranium and the metallic conductivity occurs mainly owing to the layers of copper and phosphorus. For comparison, the microscopic magnetism has been investigated in the strongly correlated electron systems CeCoIn_5(superconductor), CePt_2In_7(antiferromagnet), etc. by means of nuclear magnetic resonance technique.
