The antiferromagnetic-to-ferromagnetic transition in SrFe $_{1-x}$ CoO (0.15) induced by Co doping has been studied by magnetic circular X-ray dichroism. The orbital and spin magnetic moments of the Fe and Co 3 states under the magenetic field of 2 T are found to show different dependences: The spin polarization of Fe 3 gradually increases with Co concentration; On the other hand, a large spin polarization of Co 3 is induced already in the antiferromagnetic phase, indicating that the Co moment is nearly fully alligned already in the antiferromagnetic phase. This suggests that the alignment of the Fe magnetic moment in SrFe $_{1-x}$ CoO is induced by interaction with doped Co magnetic moment. Possible formation of ferromagnetic Co rich region is discussed.
