|Research areas||NMR study of strongly correlated electron systems, NMR under high pressure|
|Keywords||Strongly correlated electron systems (Superconductivity in metal oxsides, MI transtion systems, Low dimmensional Magnetism,...)NMRHigh pressure physics|
|Themes||We study strongly correlated electron systems by using nuclear-magnetic- resonance (NMR) techniques up to 4.0 GPa. At present, our main focuse is the NMR study on iron-based high-Tc superconducting compounds such as the La1111 systems, LaFeAsO1-xHx and LaFeAsO1-xFx.|
