Ferroelectric Transition Induced by the Incommensurate Magnetic Ordering in LiCuVO4
Yutaka Naito, Kenji Sato, Yukio Yasui +3
A ferroelectric transition occurring simultaneously with helical spin order has been found in both the polycrystalline and single crystal samples of LiCuVO4. The system has Cu2+ sp…
New Type Phase Transition of Li2RuO3 with Honeycomb Structure
Yoko Miura, Yukio Yasui, Masatoshi Sato +2
A new-type structural transition has been found in Li2RuO3 with honeycomb lattice of edge-sharing RuO6-octahedra. With decreasing temperature T, the electrical resistivity exhibits…
Successive Magnetic Transitions of the Kagome Staircase Compound Co3V2O8 Studied in Various Magnetic Fields
Yukio Yasui, Yusuke Kobayashi, Minoru Soda +4
For the spin-3/2 kagome staircase system Co3V2O8, magnetic field (H)-temperature (T) phase diagrams have been constructed for the fields along three principal directions up to 5 T,…
Existence of the Co3+ Low Spin State in TbBaCo2O5.5
Minoru Soda, Yukio Yasui, Yoshiaki Kobayashi +3
NMR studies have been carried out on a single crystal sample of TbBaCo2O5.5 with the oxygen-deficient perovskite structure. We have also carried out neutron diffraction studies and…
Studies of the Anomalous Hall Effect and Magnetic Structure of Nd2Mo2O7 -Test of the Chirality Mechanism-
Yukio Yasui, Taketomo Kageyama, Taketo Moyoshi +3
Neutron scattering studies have been carried out under the magnetic fields H//[0_11] and H//[001] on a single crystal of Nd2Mo2O7, whose Hall resistivity(rhoH) exhibits quite unusu…
Search for Magnetic Excitation Spectra of NaxCoO2.yD2O -Neutron Scattering-
Taketo Moyoshi, Yukio Yasui, Minoru Soda +3
Neutron inelastic scattering studies on aligned crystals of NaxCoO2.yD2O have been carried out. Significant scattering has been observed for phonons originating from the vibrations…
