Abstract: | An antiferromagnetic transition is observed in the quasi-one-dimensional metal-oxide compound LiCuVO4. A wide peak is observed in the temperature dependence of the magnetic susceptibility at T
M
=28 K, and the magnetic susceptibility exhibits a sharp drop at T
N
≈4 K. As the magnetic field increases, the antiferromagnetic-ordering temperature T
N
=2.3 K at first increases somewhat and then decreases rapidly. The exchange interaction in the chains of copper-oxygen octahedra
is estimated to be J
1=22.5 K. The interchain interaction is estimated to be J
2∼1 K.
