Antiferromagnetism, superconductivity, and pseudogap in three-layered high-T_c cuprates Ba_2Ca_2Cu_3O_6(F,O)_2 probed by Cu-NMR
Sunao Shimizu, Shin-ichiro Tabata, Hidekazu Mukuda +4
We report on the phase diagram of antiferromagnetism (AFM) and superconductivity (SC) in three-layered Ba_2Ca_2Cu_3O_6(F,O)_2 by means of Cu-NMR measurements. It is demonstrated th…
Planar CuO_2 hole density estimation in multilayered high-T_c cuprates
Sunao Shimizu, Shiho Iwai, Shin-ichiro Tabata +5
We report that planar CuO_2 hole densities in high-T_c cuprates are consistently determined by the Cu-NMR Knight shift. In single- and bi-layered cuprates, it is demonstrated that…
High-T_c Superconductivity with T_c = 52 K under Antiferromagnetic Order in Five-layered Cuprate Ba_2Ca_4Cu_5O_10(F,O)_2 with T_N = 175 K: 19F- and Cu-NMR Studies
S. Shimizu, S. -i. Tabata, H. Mukuda +4
We report on the observation of high-T_c superconductivity (SC) emerging with the background of an antiferromagnetic (AFM) order in the five-layered cuprate Ba_2Ca_4Cu_5O_10(F,O)_2…
Novel Superconducting Phases in Copper Oxides and Iron-oxypnictides: NMR Studies
Yoshio Kitaoka, Hidekazu Mukuda, Sunao Shimizu +3
We reexamine the novel phase diagrams of antiferromagnetism (AFM) and high-Tc_2$ plane based on an evaluation of local hole densi…
