Abstract

Recent NMR measurements on high-T c materials by our group are reviewed. Study of YBa 2Cu 3O 7+Ni has revealed that the attractive force is spin in origin. Analysis of T 1, the Knight shift K and T 2G in Tl 2Ba 2Ca 2CuO 10 (T12223), HgBa 2Ca 2Cu 3O 8 (Hg1223), HgBa 2Ca 3Cu 4O 10 (Hg1234) and YBa 2Cu 4O 8 (Y1248) supports the antiferromagnetic spin fluctuation (AFSF)-rnediated-superconductivity-model. The temperatures at which a pseudogap starts to open obtained by 1/T 1T, dK/dT, photoemission, resistivity and STM all agree with each other in Bi 2Sr 2CaCu 2O 8 (Bi2212). The origin of the pseudogap is discussed.
