| Research Abstract |
On and around the triangular lattice and pyrochlore lattice, we searched the new itinerant electronic compounds which show the novel quantum phenomena. As the results, we successfully draw the electronic phase diagram of cobalt oxide superconductor and of Pb_3V_4O_9, and in the Fe (Te, Se) system, one of the iron-based superconductors, we clarified the existence of magnetic fluctuations which are important for the realization of superconductivity by utilizing the NMR.
