摘要：

The magnetic behaviour of Nd2BaCoO5 has been studied by means of neutron powder diffraction at low temperatures. The magnetic structure is antiferromagnetic and can be described on the basis of a wave vector k = [1/2, 0, 1/2] with a B-g magnetic mode, T-N similar to 24 K being the estimated Neel temperature. The Nd3+ magnetic moments are parallel to the crystallographic c-axis and the Co2+ magnetic moments lie in the ac plane oriented along the a-axis with a small canting in the z direction. Their values at 1.5 K are 2.55(4)mu(B) and 3.08(7)mu(B), respectively.
