Outline of Final Research Achievements

For the understanding of the relation of the antiferromagnetic coupling between Cu spins with the high-temperature superconducting mechanism and the origin of pseudogap phenomenon in cuprates, we performed STM/STS experiments at T<<Tc in pure and Ni-impurity doped Bi-based high-Tc cuprates, and also tried to make ARPES experiments. In high-Tc cuprates, it is well-known that the suppression effect on the superconductivity due to impurities is much weaker for magnetic Ni than for nonmagnetic Zn. The present study has demonstrated that such anomalous impurity effect on the high-Tc superconductivity can be explained in terms of the impurity effect on the antiferromagnetic coupling of Cu-spins. Furthermore, we have also obtained some results suggesting that the antiferromagnetic coupling is responsible for the pairing mechanism in high-Tc cuprates.
