| Research Abstract |
We have developed site-selective NMR techniques from the viewpoints of In-situ and Ex-situ NMR to study the local magnetism of quantum interference bound states inside vortex cores in the mixed states of type II superconductors.We found the inhomogeneous magnetic correlation of Ca_2-xNa_xCuO_2Cl_2, a magnetic differentiation phenomenon at the superconducting transition for Hg1223, and frequency distribution of spin correlation in the broad NQR spectrum of Bi2212 below T_c.
