A neutron powder diffraction study revealed that Ca2Y2Cu5O10, which consists of edge-sharing CuO2 chains, shows an antiferromagnetic long-range ordering below ∼29K. The arrangement of the Cu2+ spins is ferromagnetic along the chain (a axis) with a spin direction along the b axis. The magnetic structure has the propagation vector k = [001]. The ordered moment of the Cu2+ spins is ∼0.9 μB at 10K, suggesting that the interchain interactions are fairly large. The observed intensities can be better described by assuming an ordering of oxygen moments which aie induced due to the strong hybridization between the copper and oxygen ions.
