| 摘 要： | 采用电弧熔炼法制备了金属间化合物PrMn6Sn6.X射线衍射表明该化合物具有HoFe6Sn6型(空间群为Immm)晶体结构.磁测量表明该化合物为铁磁性，居里温度为325 K.在15—360 K范围内测量了119Sn穆斯堡尔谱，得到了8个Sn原子晶位的转移超精细场随温度的变化，并且讨论了Mn亚晶格与Pr亚晶格的磁有序方向.

| Abstract: | The intermetallic compound PrMn6Sn6 was prepared by arc-melting and showed a HoFe6Sn6-type (group space: Immm) structure. The compound is ferromagnetic, where the Mn- and Pr-sublattices are ferromagnetically coupled,and has a Curie temperature of 325 K. The 119Sn Mssbauer spectra between 15 and 360 K were measured, and were analyzed by a simplified model according to the eight Sn crystallographic sites with different nearest-neighbors environment, and the corresponding transferred hyperfine fields and the average value dependence on temperature were obtained. The magnetic structure of the two sublattice is discussed. |
