A pseudobinary alloy of CaMn $_{1-x}$ Ru $_{x}$ O $_{3}$ (CMRO) is interesting because the solid solution CMRO shows a metallic ferromagnetism although both of the end compositions does not show ferromagnetism. We have fabricated the epitaxial CMRO thin films using the pulsed laser deposition (PLD) method, and studied the ferromagnetic moments by soft X-ray absorption magnetic circular dichroism (XMCD) measurements. The XMCD studies indicated that the spin moments of Mn and Ru are aligned in antiparallel directions. We consider that the small total magnetic moment of CMRO results from the cancellation of the Ru spin moment from Mn spin moment.
