摘要：

We present inelastic neutron scattering measurements of the low temperature magnetic excitations associated with Nd ordering in single crystalline Nd2CuO4. At T=1.5 K, four distinct, weakly dispersive, low lying modes around 0.05, 0.09, 0.14, and 0.20 THz are observed. The implications of these measurements on a recently proposed RPA calculation are discussed. Copyright (C) 1996 Published by Elsevier Science Ltd
