We have employed the x-ray resonant magnetic scattering (XRMS) technique at the Ru L2 edge of the Ba(Fe_1\ensuremath-xRux)2As2 (x=0.205) superconductor. We show that pronounced resonance enhancements at the Ru L2 edge are observed at the wave vector which is consistent with the antiferromagnetic propagation vector of the Fe in the undoped BaFe2As2. We also demonstrate that the XRMS signals at the Ru L2 edge follow the magnetic ordering of the Fe with a long correlation length, \ensuremathξab>2850\ifmmode±\else\textpm\fi400 \AA. Our experimental observation shows that the Ru is spin polarized in Ba(Fe_1\ensuremath-xRux)2As2 compounds.
