摘要：

Neutron scattering measurements have been performed on the S=1/2 quasi-one-dimensional system La5Ca9Cu24O41, which consists of edge-sharing CuO4 chains. We observed that the chains shaw an antiferromagnetic long-range ordering below T-N=10.5 K with ferromagnetic correlations within the chain. In the antiferromagnetically ordered phase, an ordering of oxygen moments (similar to 0.02 mu(B)) as well as that of Cu moments (similar to 0.2 mu(B)) is observed. The oxygen moments are coupled with Cu moments ferromagnetically.
