摘要：

Neutron scattering measurements have been performed on a single crystal of Ca2CuO3, an S = 1/2 quasi-one-dimensional(1D) antiferromagnet. A three-dimensional (3D) antiferromagnetic long range order was observed below 8 K with an antiparallel Cu spin alignment within the Cu-O chain and between the nearest neighbor spins on the different chains. The anomalously small ordered moment of about 0.05 mu(B) might originate from the large energy scale of the spin fluctuation.
