论文摘要
研究了在磁性中子衍射中观察的三角对称性中的电子多物。所有磁多物的分析表达式以及用已建立的原子密码计算的径向积分，用于审查最近的主张，以观察到在Pyrochlore CE2SN2O7的粉末样品中观察到了八杆冰构型。属于不相关元素的多个多数套件同样令人满意地说明了可用的衍射模式。我们的多物适用于使用Bragg衍射的将来的实验，该化合物支持远程磁性。
Cerium electronic multipoles in trigonal symmetry viewed in magnetic neutron diffraction are investigated. Analytic expressions for all the magnetic multipoles, and radial integrals calculated with an established atomic code, are used to scrutinize a recent claim to have observed an octupole-ice configuration in a powder sample of pyrochlore Ce2Sn2O7. Three equally plausible suites of multipoles belonging to uncorrelated cerium ions give equally satisfactory accounts of the available diffraction pattern. Our multipoles are suitable for future experiments using Bragg diffraction from a compound that supports long-range magnetic order.
