Abstract

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 T_N = 482 and 527 K, respectively. The compound YMn₆Ge₆ saturates at M _s = 12 μ_B/f.u. above 33 T, whereas LuMn ₆Ge₆ is still not saturated in the largest applied field (M(50 T) = 9 μ_B/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.
