Taisuke Hattori,Yoshihiko Ihara,Yusuke Nakai,Kenji Ishida,Yasuhiro Tada,Satoshi Fujimoto,Norio Kawakami,E. Osaki,Kazuhiko Deguchi,Noriaki K. Sato,Isamu Satoh +10 more
TL;DR: It is found that magnetic fields along the c axis (H∥c) strongly suppress the FM fluctuations and that the superconductivity is observed in the limited magnetic-field region where the longitudinal FM spin fluctuations are active.
Journal ArticleDOI
Unconventional Superconductivity and Nearly Ferromagnetic Spin Fluctuations in NaxCoO2·yH2O
K Ishida,Yoshihiko Ihara,Yoshiteru Maeno,Chishiro Michioka,Masaki Kato,Kazuyoshi Yoshimura,Kazunori Takada,Takayoshi Sasaki,Hiroya Sakurai,Eiji Takayama-Muromachi +9 more
TL;DR: In this paper, a superconductor Na x CoO 2 · y H 2 O was investigated to investigate physical properties in the superconducting (SC) and normal states, and it was found that the coherence peak is absent just below T c and that 1/T 1 is proportional to temperature far below t c.
Journal ArticleDOI
Unconventional Superconductivity and Nearly Ferromagnetic Spin Fluctuations in Na$_x$CoO$_2$$\cdot y$H$_2$O
Kenji Ishida,Yoshihiko Ihara,Y. Maeno,Chishiro Michioka,Masaki Kato,Kazuyoshi Yoshimura,Kazunori Takada,Takahiko Sasaki,Hiroya Sakurai,E. Takayama-Muromachi +9 more
TL;DR: In this article, the nuclear-spin lattice relaxation rate (NQR) of superconducting and normal superconductor Na$_x$CoO$_2$$\cdot y$H $_2$O to investigate physical properties in the SC and normal states was performed.
Journal ArticleDOI
Spin dynamics and spin freezing behavior in the two-dimensional antiferromagnet Ni Ga 2 S 4 revealed by Ga-NMR, NQR and μ SR measurements
H. Takeya,Kenji Ishida,Kentaro Kitagawa,Kentaro Kitagawa,Yoshihiko Ihara,Keisuke Onuma,Yoshiteru Maeno,Yusuke Nambu,Yusuke Nambu,Satoru Nakatsuji,Satoru Nakatsuji,D. E. MacLaughlin,A. Koda,Ryosuke Kadono +13 more
TL;DR: In this article, two distinct Ga signals by NMR and NQR were found to be generated by stacking faults along the $c$ axis which induce additional broad Ga NMR signals with different local symmetries.
Journal ArticleDOI
NMR study of the Mott transitions to superconductivity in the two Cs3C60 phases.
TL;DR: A NMR and magnetometry study on the expanded intercalated fulleride Cs3C60 in both its A15 and face centered cubic structures shows that the interball distance is the relevant parameter driving the electronic behavior and quantum transitions of these systems.
