In the intermetallic compound Gd(Fe_<0.9>Co_<0.1))_2, the change in the ^<59>Co hyperfine field upon hydrogen absorption has been investigated by means of NMR measurement. In the NMR spectra of Gd(Fe_<0.9>Co_<0.1>)_2H_y, many peaks which seem to be attributed to Gd atoms and Co atoms were observed. The appearance of many peaks are analyzed using a local environment effect and the change of Co moment upon hydrogen absorption are estimated. ln conclusion, it was found that there are several types of ^<59>Co hyperfine fields in Gd(Fe_<0.9>Co_<0.1>)_2-hydrides.
