Outline of Final Research Achievements

We have studied the relationship between superconductivity and magnetism on strongly correlated electron superconductors located near magnetic phase with nuclear magnetic resonance (NMR)/ nuclear quadrupole resonance (NQR). In this research project, we have focused on ferromagnetic superconductor UCoGe and iron-based superconductor BaFe2(As1-xPx)2 and investigated the coexistence of superconductivity and magnetic ordering and the role of the magnetic fluctuations for the occurrence of superconductivity from the microscopic point of view.
We obtained following results on UCoGe: 1)Superconductivity and magnetism coexist microscopically in UCoGe. 2)From the nuclear spin-lattice relaxation rate 1/T1 measurements in three directions and under various magnetic fields, Ising ferromagnetic fluctuations in UCoGe play an important role in superconductivity, which presumably pairing glue for superconductivity. 3) Thus, the pairing symmetry of UCoGe would be spin triplet.
