摘要：

We have measured the complete crystalline electric field (CEF) spectrum of Nd3+ in superconducting Nd1.85Ce0.15CuO4 and Nd2CuO3.7F0.3, and in the non-superconducting parent compound, Nd2CuO4, by neutron inelastic scattering. The best description of the ground-state excitations for both compounds is achieved by the addition of a molecular field parameter to the CEF hamiltonian that takes account of exchange interactions from Nd or Cu spin ordering.
