我们提出的晶体结构和磁化强度的研究结果，从不同的名义组成的熔体生长在附近的Lu 2Fe 17化学计量的三个单晶。晶体的铁磁状态强烈地依赖于真实的样品成分和局部原子有序。一个显着的差异是观察到的铁-反铁磁过渡的行为，即使在晶体中，几乎相同的组成和晶体参数，由微探针和X-射线分析确定。
We present the results of crystal structure and magnetization studies of three single crystals grown from melts of different nominal compositions in the vicinity of the Lu2Fe17stoichiometry. The ferromagnetic state of the crystals is strongly dependent on the real sample composition and the local atomic ordering. A drastic difference is observed in the behaviour of the ferro–antiferromagnetic transition, even in crystals for which almost identical composition and crystal parameters were determined by microprobe and X-ray analysis.
