NMR and Neutron Scattering Studies of Quasi One-Dimensional Magnet   CuV_2O_6
  Magnetic properties of a quasi one-dimensional magnet CuV_2O_6 have been studied by means of susceptibility measurement, NMR and powder neutron diffraction. Cu^{2+} spins (S=1/2) order antiferromagnetically below 22.6 K, and the saturation moment is about 0.70 \mu_{B} at 0 K. The magnetic structure determined in the present study indicates that in CuV_2O_6 one-dimensional antiferromagnetic spin chains are along [110], suggesting a dominant antiferromagnetic exchange interaction between the next-nearest-neighbor spins rather than the nearest-neighbor ones.
