摘要：

Neutron-diffraction investigations have been performed to determine the magnetic ordering of Cu ions in a Gd-158-enriched Gd2CuO4 single crystal. The Cu magnetic moments in Gd2CuO4 are found to order at about 285 K to an antiferromagnetic; structure with the propagation vector k = (1/2, 1/2, 0). The antiferromagnetic structure is similar to that of La2NiO4. The magnetic moments of Cu ions are oriented parallel to [110].
