摘要：

Magnetic neutron scattering experiments have been performed on a single crystal of Nd2CuO4 in the temperature range 1.5-300 K in order to investigate the magnetic moments of Cu2+ and Nd3+ and their respective roles in the magnetic structures observed below T(N) = 260 K. Our results show that a magnetic moment is present on Nd3+ in all three phases. The magnitude of this moment increases with decreasing temperature, whereas some Nd-Cu spin correlations change abruptly at the I-II and II-III phase transitions.
