Helicoidal magnetic order in a clean copper oxide spin chain compound
L. Capogna, M. Mayr, P. Horsch +6
We report susceptibility, specific heat, and neutron diffraction measurements on NaCuO, a spin-1/2 chain compound isostructural to LiCuO, which has been extensively…

Charge Order Driven spin-Peierls Transition in NaV2O5
Y. Fagot-Revurat, M. Mehring, R. K. Kremer
We conclude from 23Na and 51V NMR measurements in NaxV2O5(x=0.996) a charge ordering transition starting at T=37 K and preceding the lattice distortion and the formation of a spin…
