摘要：
The magnetic behaviour of Nd2BaCuO5 oxide has been studied by means of neutron powder diffraction at low temperatures. This oxide behaves as antiferromagnetic with a Neel temperature of 7.8 K, and the magnetic structure can be described on the basis of a propagation vector k = [0, 0, 1/2]. The Cu2+ magnetic moments are aligned along the c-axis of the crystal structure, while the Nd3+ magnetic moments lie in the ab-plane. The experimental values of the ordered moments at 1.7 K are 0.84 (8) and 0.78 (4)AB for copper and neodymium ions, respectively. (c) 2005 Elsevier B.V. All rights reserved.
