Orbital and spin chains in ZnV2O4
S. -H. Lee, D. Louca, H. Ueda +8
Our powder inelastic neutron scattering data indicate that \zvo is a system of spin chains that are three dimensionally tangled in the cubic phase above 50 K due to randomly occupi…

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…

Commensurate spin dynamics in the superconducting state of an electron-doped cuprate superconductor
K. Yamada, K. Kurahashi, T. Uefuji +4
We report neutron scattering studies on single crystals of the electron-doped (n-type) superconducting cuprate Nd2-xCexCuO4 (x=0.15) with Tc = 18 K and 25 K. Unlike the hole-doped…
