摘要：

The antiferromagnetic structure of the Cu spins and the Neel point in Y2BaCuO5 were redetermined by neutron powder diffraction. There are two possible collinear models with wave vector k = [0, 1/2,1/2] and the spins directed along the c-axis. These models cannot be distinguished in powder diffraction. The ordered magnetic moment of the copper atom at saturation amounts to 0.55(3)mu(B).
