The magnetism of CaRu{sub 1-x}Mn{sub x}O{sub 3} was studied using magnetic Compton scattering measurements for polycrystalline specimens at 10 K under 2.5 T using a synchrotron-radiation x ray. The spin moment deduced from the magnetic Compton profiles has a maximum at x=0.7 and the value agrees with the result of the magnetization measurement. The magnetic Compton profiles indicate that the Mn spin moment is dominant in magnetization and that Ru moment, which is induced with Mn doping, couples with Mn spin moment antiferromagnetically. The results suggest that a sort of ferrimagnetism is established in the CaRu{sub 1-x}Mn{sub x}O{sub 3} system.
