Raman scattering due to a one-magnon excitation process in
S. Miyahara, K. Takubo, T. Suzuki +2
Unconventional peak structure in the Raman spectra due to magnon excitation at low temperature is observed in spinel magnet , where a noncollinear spin state is rea…
Electronic Structure of Charge- and Spin-controlled Sr_{1-(x+y)}La_{x+y}Ti_{1-x}Cr_{x}O_{3}
H. Iwasawa, K. Yamakawa, T. Saitoh +6
We present the electronic structure of Sr_{1-(x+y)}La_{x+y}Ti_{1-x}Cr_{x}O_{3} investigated by high-resolution photoemission spectroscopy. In the vicinity of Fermi level, it was fo…
Charge dynamics of Ca_{2-x}Na_{x}CuO_{2}Cl_{2} as a correlated electron system with the ideal tetragonal lattice
K. Waku, T. Katsufuji, Y. Kohsaka +6
We report the reflectivity and the resistivity measurement of Ca_{2-x}Na_{x}CuO_{2}Cl_{2} (CNCOC), which has a single-CuO2-plane lattice with no orthorhombic distortion. The doping…
Universal charge transport of the Mn oxides in the high temperature limit
W. Kobayashi, I. Terasaki, M. Mikami +3
We have found that various Mn oxides have the universal resistivity and thermopower in the high temperature limit. The resistivities and thermopowers of all the samples go toward c…
Unconventional spin fluctuations in the hexagonal antiferromagnet YMnO
T. J. Sato, S. -H. Lee, T. Katsufuji +4
We used inelastic neutron scattering to show that well below its Néel temperature, , the two-dimensional (2D) XY nearly-triangular antiferromagnet YMnO has a promi…
