Temperature dependence of magnetic susceptibility of U_{1-x}Ce_{x}Ru _{2}Si_{2} single crystals (x=0, 0.025, 0.05, 0.075) has been studied at temperatures from 4.2 K up to room temperature and in magnetic fields applied along and perpendicular to the c-axis. The attention was paid to anomalies connected with the antiferromagnetic phase transition, which are present in crystals with x≤0.05. Far-infrared measurements of U_{0.99}Ce_{0.01} Ru_{2}Si_{2} single crystal have been studied for the first time. The measurements support the assumption that the origin of magnetic ordering in U_{0.99}Ce_{0.01}Ru_{2}Si_{2} is the same as in heavy-fermion superconductor URu_{2}Si_{2} and can be interpreted as being due to a spin-density-wave gap.
