abstract = {Magnetic susceptibility measurements have shown that the compounds Mn 1-x Fe x Ge  are magnetically ordered through the whole range of concentrations x=[0.0,1.0] . Small-angle neutron scattering reveals the helical nature of the spin structure with a wave vector, which changes from its maximum (|k|=2.3  nm −1  ) for pure MnGe, through its minimum (|k|→0 ) at x c ≈0.75 , to the value of |k|=0.09  nm −1   for pure FeGe. The macroscopic magnetic measurements confirm the ferromagnetic nature of the compound with x=x c  . The observed transformation of the helix structure to the ferromagnet at x=x c   is explained by different signs of chirality for the compounds with x>x c   and x<x c  . We used x-ray diffraction and polarized neutron scattering to evaluate the crystallographic chirality Γ c   and the magnetic chirality γ m   of the FeGe single crystals. Similar to previous observations for FeSi-based compounds, FeGe demonstrates left- (right-)handed crystalline chirality acompained by right (left) handedness of the magnetic helix (Γ c γ m =−1 ). At variance, MnSi related compounds show the opposite behavior (Γ c γ m =1 ). Since the magnetic chirality γ m   relates to the sign of the Dzyaloshinskii-Moriya interaction (DMI), for the same geometrical arrangement (Γ c  ) the sign of DMI can be set by the proper choice of the transition metal.},
