Abstract

Recent NMR measurements on high-T_c and related material Sr₂RuO₄ by the Osaka group are reviewed. The following results are presented: (1) Study of YBa₂Cu₃O₇ + Ni has revealed that the attractive force is spin in origin. (2) Analysis of T₁, T₂ and Knight shift (K) in various high-T_c materials supports the antiferromagnetic spin-fluctuation mediated superconducting model. (3) Temperatures at which a pseudogap starts to open obtained by 1/T₁T, dK/dT, photoemission and resistivity agree with each other in the Bi₂Sr₂CaCu₂O_8+δ system. (4) ¹⁷O Knight shift measurements in the related material Sr₂RuO₄ suggests that a triplet pairing is realized in this compound as in the heavy-fermion superconductor UPt₃.
