对同型化合物ce3ni2g7和ce3ni2sn7进行了电阻率和磁化测量。在tn =7.0(2) K以下，三元锗化物具有反铁磁序，比ce3ni2sn7 [tn =3.8(2) K]的Neel温度高。这项研究提出了存在于Ce- ni - sn体系中的三元化合物的Ce价与最小原子间距离d Ce- ni和d Ce- sn之间的直接关系。
Electrical resistivity and magnetization measurements have been performed on the isotypic compounds Ce 3 Ni 2 Ge 7 and Ce 3 Ni 2 Sn 7 . The ternary germanide orders antiferromagnetically below T N =7.0(2) K, a Neel temperature higher than that observed for Ce 3 Ni 2 Sn 7 [T N =3.8(2) K]. This investigation allows proposal of a direct relationship between the Ce valence and the smallest interatomic distances d Ce-Ni and d Ce-Sn for the ternary stannides existing in the Ce-Ni-Sn system.
