TL;DR: In this paper, a number of stannides were synthesized from the elements and their magnetic properties were studied in the temperature range 4.2 K < T < 900 K. All the compounds are isotypic and crystallize in the HfFe6Ge6 type structure.

TL;DR: The magnetic properties of ThCr2Si2-type structure RMn2Ge2 (R = Ce, Pr, Nd) compounds have been investigated by the use of neutron diffraction experiments.

TL;DR: In this article, the iron and manganese germanides RT 6 Ge 6 (RSc, Y, Nd, Sm, Gd, TbFe 6 Sn 6) have been investigated by X-ray diffraction and susceptibility measurements in the temperature range 90-900 K.

TL;DR: In this paper, the thermal dependence of the Mn sublattice magnetic orderings within the RMn 2 X 2 (X = Si, Ge) compounds is proposed, and the occurrence of an in-plane antiferromagnetic Mn component (obviously correlated with a critical MnMn intralayer spacing value of ∼ 2.87 A ) over the whole ordered range leads to strongly revise the ferromagnetic ordering previously proposed to take place in such compounds.

TL;DR: In this article, two new germaniures binaires are introduced: LuGe 2 and TmGe 2, isotypes de ZrSi 2, which are non-stoechiometriques, avec de larges domaines d'homogeneite.
