Magnetic Excitations of Spin-Gap System Na3Cu2SbO6 with Distorted Honeycomb Structure
Yoko Miura, Yukio Yasui, Taketo Moyoshi +2
Magnetic excitation spectra of quantum spins of Na3Cu2SbO6 with the distorted honeycomb structure have been measured by neutron inelastic scattering. The intensity distribution and…
NMR studies of Successive Phase Transitions in Na0.5CoO2 and K0.5CoO2
Mai Yokoi, Yoshiaki Kobayashi, Taketo Moyoshi +1
59Co- and 23Na-NMR measurements have been carried out on polycrystalline and c-axis aligned samples of Na0.5CoO2, which exhibits successive transitions at temperatures T = 87 K (=…
Co-NMR Knight Shift of NaxCoO2 \dot yH2O Studied in Both Superconducting Regions of the Tc-nuQ3 Phase Diagram Divided by the Nonsuperconducting Phase
Yoshiaki Kobayashi, Taketo Moyoshi, Mai Yokoi +1
In the temperature (T)-nuQ3 phase diagram of NaxCoO2 \dot yH2O, there exist two superconducting regions of nuQ3 separated by the nonsuperconducting region, where nuQ3 is usually es…
Studies of the Anomalous Hall Effect and Magnetic Structure of Nd2Mo2O7 -Test of the Chirality Mechanism-
