N2 - The magnetic properties of single crystals of the HfFe6Ge 6-type compounds YMn6Ge6 and LuMn 6Ge6 obtained in an In flux have been investigated by thermomagnetic measurements and by a high-field magnetization study. Both the compounds display Néel point at TN = 482 and 527 K, respectively. The compound YMn6Ge6 saturates at M s = 12 μB/f.u. above 33 T, whereas LuMn 6Ge6 is still not saturated in the largest applied field (M(50 T) = 9 μB/f.u.), thus indicating different strengths of the antiferromagnetic interactions. The magnetization curves of YMn 6Ge6 and LuMn6Ge6 recorded with the field applied along the c-axis display a field-induced transition at relatively low field (around 10 and 15 T, respectively), which should be related to spin reorientation process. In larger applied fields, all magnetization loops display two field-induced transitions with pronounced hysteretic behaviour which may be related to the successive stabilization of helical and fan structures.
