  57Fe Mossbauer spectroscopy measurements were performed on a powdered
CuFe2Ge2 sample that orders antiferromagnetically at ~ 175 K. Whereas a
paramagnetic doublet was observed above the Neel temperature, a superposition
of paramagnetic doublet and magnetic sextet (in approximately 0.5 : 0.5 ratio)
was observed in the magnetically ordered state, suggesting a magnetic structure
similar to a double-Q spin density wave with half of the Fe paramagnetic and
another half bearing static moment of ~ 0.5 - 1 mu_B. These results call for a
re-evaluation of the recent neutron scattering data and band structure
calculations.
