Pie分析了CeB 6相II中B-11-NMR谱的共振场与磁场的角度依赖关系。实验结果很好地解释为磁偶极和转移的超精细场从Ce网站的总和。后者是从唯象引入八极矩的超精细场的微观起源。结果表明，不寻常的温度和磁场依赖性的共振场在低场在第二阶段起源于反铁磁矩通过偶极场，是一致的中子散射的结果。
Pie analyze the angular dependence of the resonance field of B-11-NMR spectrum with respect to the magnetic field in phase II of CeB6. The experimental results are well explained as a sum of the magnetic dipolar and the transferred hyperfine field from the Ce site. The latter is the microscopic origin of the hyperfine field from the octupolar moment introduced phenomenologically. It is shown that the unusual temperature and magnetic field dependence of the resonance field at low fields in phase II originates from that of the antiferromagnetic moment through the the dipolar field and is consistent with the neutron scattering results.
