Resumo: X-ray diffraction, ac susceptibility and 57Fe Mössbauer spectroscopy measurements have been performed in the MgC(Ni1-xFe x )(0 <= x <= 0.5) series. The superconducting transition temperature Tc of the undoped sample, determined by ac susceptibility, is <FONT FACE=Symbol>~</FONT> 7K. The Fe doping quickly depresses Tc, completely destroying the superconducting state for x <FONT FACE=Symbol>~</FONT> 0.04. The establishment of an ordered magnetic state is only observed for Fe concentration (x > or = 0.3) far above the concentration for which the superconducting state has completely disappeared. An expansion of the lattice with the increase of the Fe content was observed.
