Neutron powder diffraction study on Nd2BaCuO5 oxide
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, 1/21. The Cu2+...

| Zusammenfassung: | 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, 1/21. 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)mB for copper and neodymium ions, respectively. |
