59Co NMR of (U1-xNdx)Co2Ge2 (x = 0, 0.25, 0.5, 0.75, 1) was studied in an external field of 8.0196 T in the temperature range of 5-300 K. Three well distinguished regions, corresponding to the paramagnetic, intermediate, and antiferromagnetically ordered states of these compounds, were observed, in a good agreement with neutron diffraction, AC-susceptibility, and SQUID magnetization measurements. Using the results for paramagnetic region, the coefficients of indirect exchange interaction between conduction and f-electrons in these compounds were determined as -0.06(3) and -0.16(9) eV, for U and Nd, respectively.
