- As in the case of TbCr6Ge6, these isotherms show a tendency towards saturation at low fields already.
- An interpretation of these curves is, however, more difficult than in the case of TbCr6Ge6, because no clear indication of magnetic ordering was obtained for these materials from the temperature dependence of the magnetization.

TL;DR: A review of the current knowledge concerning the phase diagrams and crystal structures of ternary metal germanides with the R elements can be found in this paper, where the authors describe the isothermal sections and crystallographic characteristics of the compounds and outline the experimental methods that have been utilized.
Abstract: Publisher Summary This chapter reviews the current knowledge concerning the phase diagrams and crystal structures of ternary metal germanides with the R elements. It describes the isothermal sections and crystallographic characteristics of ternary compounds and outlines the experimental methods that have been utilized. While no phase diagram is available for the Ce–Ga–Ge system, the X-ray phase analysis of 180 ternary alloys indicated the formation of four ternary compounds in the Ce–Ga–Ge system. No phase diagram has been constructed for the ternary Ho–A1–Ge system; however, data on the formation and crystal structure of three compounds exist because of the independent investigations of research groups from L’viv University and Geneva University.

TL;DR: In this paper, the hexagonal compound DyMn 6 Ge 6 has been studied by neutron diffraction at various temperatures between T N = 420 K and 11 K and the phase transition at about 100 K is shown to be of second order and marks the transition from a triple flat spiral structure stable at high temperatures to a triple conical structure stable in low temperatures.

TL;DR: In this paper, the intrinsic anomalous Hall effect (AHE) was observed for single crystals of the Mn-based kagome lattices of high-temperature ferromagnetic compounds.
Abstract: We report magnetic and electrical properties for single crystals of $\mathrm{Nd}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ and $\mathrm{Sm}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$. They crystallize into a structure that has distorted, Mn-based kagome lattices, compared to the pristine kagome lattices in heavy rare-earth-bearing $\mathrm{R}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ compounds. They are high-temperature ferromagnets of which the R moment is parallel with the Mn moment. We observed a large intrinsic anomalous Hall effect (AHE) that is comparable to the ferrimagnetic, heavy-R siblings in a wide range of temperature. We conclude that their intrinsic AHE is stemming from the Mn-based kagome lattice, just as in the heavy $\mathrm{R}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$.
