ResumoThe magnetic properties of CrGe alloys have been investigated by neutron diffraction measurements. An addition of Ge to Cr increases the Néel temperature, the magnetic moment and the wave vector of the spin density wave (SDW). The commensurate SDW phase appears in the alloys containing Ge impurities more than 1 at.%. The observed features are discussed on the basis of the two band nesting model supposing that the Ge atom in Cr acts as electron donor and also on the model in which the Ge atom in Cr acts as the magnetic vacancy.
