摘要：
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 TM=28 K, and the magnetic susceptibility exhibits a sharp drop at TN≈4 K. As the magnetic field increases, the antiferromagnetic-ordering temperature TN=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 J1=22.5 K. The interchain interaction is estimated to be J2∼1 K.
