| Outline of Final Research Achievements |
(1)NMR study of Sr2VFeAsO3 under high pressure; In iron based high temperature superconductor Sr2VFeAsO3, we found an antiferromagnetic order above Tc and obtained novel pressure-temperature phase diagram of superconductivity and antiferromagnetism. (2)High temperature NMR study in SrPt2As2 superconductor; We found multiple charge density wave orders in SrPt2As2, which coexist with superconductivity by NMR measurement up to 600K. (3)High pressure NQR and resistivity measurements on CeRhIrIn5; We found that a unconventional superconducting state is induced near the antiferromgnetic quantum critical point in CeRhInIn5. (4)NMR study in Ce1-xLaxFeAs2; We found electron doping enhanced antiferromagnetism and its coexistence with high temperature superconductivity in Ce1-xLaxFeAs2. (5) High field NMR study in high Tc cuprate; By applying high magnetic field up to 45T, we found a CDW order is induced after suppressing superconductivity in underdoped cuprate.
