摘要：

Neutron diffraction experiments performed for YbN in the temperature range from 7 mK to room temperature prove the existence of long-range f.c.c. antiferromagnetic ordering of type III below TN=(0.790±0.005) K. The low ordered magnetic moment of Yb at saturation, μ=(0.39±0.05)μ> B, is presumably caused by Kondo hybridization. By means of inelastic neutron scattering the crystalfield level scheme was established to be Γ6 -Γ8(33 meV)-Γ7(81 meV). The Γ6 -Γ8 transition was found to be split into two lines which may be due to a bound state between the crystal-field excitation and phonons. © 1990 Springer-Verlag.
