We have studied the electronic and magnetic properties of epitaxially grown CaMn$$_{1-x}$$Ru$$_{x}$$O$$_{3}$$ (x = 1.0, 0.5) thin films by X-ray magnetic circular dichroism (XMCD) and hard X-ray photoemission spectroscopy (HXPES). The XMCD studies indicated that the spin moments of Mn and Ru are aligned in the opposite directions. The HXPES spectra indicated the Ru 4d states at around the Fermi edge (E$$_{F}$$) and the Mn 3d states below E$$_{F}$$. From these results, we propose that the localized Mn 3d t$$_{2g}$$ states and the itinerant Ru 4d t$$_{2g}$$ band are antiferromagnetically coupled and give rise to ferromagnetism, in analogy with the mechanism proposed for the double perovskite oxides such as Sr$$_{2}$$FeMoO$$_{6}$$.
