UCoGe is an archetype of coexisting weak itinerant 5f-electron ferromagnetism (T_{C}~3 K, μ_{s}=0.03μ_{B}/f.u.) and superconductivity (T_{SC}~ 0.6 K) at ambient pressure. The Ru substitution for Co leads to an initial sharp increase of the T_{C} up to the maximum of T_{C}=8.5 K for x=0.12, increase of spontaneous magnetic moment and suppression of superconductivity. We have grown the UCo_{0.88}Ru_{0.12}Ge single crystal and studied magnetization along the principal crystallographic axes. To see the microscopic background of these findings we performed a polarized neutron diffraction experiment on D3 diffractometer in ILL. We have found that the Co and U moments are parallel in UCo_{0.88}Ru_{0.12}Ge, in contrast to the antiparallel configuration in UCoGe. This is probably the reason of the spontaneous magnetization increase with Ru doping.
