摘要：

Neutron spectroscopy experiments were performed on the cubic CsC1-type rare-earth intermetallics Pr.25La.75Mg, Pr.25La.75Zn, Nd.25La.75Mg and Nd.2La.8Zn. Crystal field parameters were deduced, but some ambiguities remain. A neutron diffraction study of PrMg is also reported : PrMg is an antiferromagnet with a moment μAF = 2.7 μB parallel to the propagation vector q = [0, 0, 1 2] ; a strong quadratic distortion occurs in the ordered state, reaching c a - 1 = 1.4% at 4.2 K. The crystal field determinations on the four compounds are analyzed in relation to their magnetic properties. © 1978.
