A transition from CeCoGe₃ to the CeFeGe₃ compound, i.e. the CeCo_{1-x}Fe_xGe₃ series has been studied by magnetoresistance measurements. Previously, it was reported that at the concentration x ≈ 0.6 the system is in the vicinity of the quantum critical point. In the present research we have performed the isothermal magnetoresistivity investigations (down to 2K) on polycrystalline samples with x = 0.3, 0.4, and 0.6 to gain further insight into the possible existence of quantum critical point in the CeCo_{1-x}Fe_xGe₃ series. Additionally, electrical resistivity as a function of temperature has been measured and analyzed showing features of non-Fermi liquid behavior at low temperatures.
