The occurrence of ferromagnetism was studied in the Ca Ru1-x Fex O3 system by means of magnetic Compton scattering; Mössbauer effect; and magnetization measurements using polycrystalline specimens. Ferromagnetism is induced for extremely small Fe doping (x≥0.02) to paramagnetic CaRu O3; and the TC increases as the Fe content increases. The temperature dependence of reciprocal magnetic susceptibility shows a characteristic of ferrimagnetism. A sextet with an isomer shift of the Fe3+ ion and the hyperfine field of about 450 kOe were observed in the Mössbauer effect measurement below TC; suggesting the existence of magnetic order. The magnetic Compton scattering experiment revealed the occurrence of a large magnetic moment on Ru and an antiferromagnetic coupling between Fe and Ru spin moments. A possible model for the occurrence of ferrimagnetism has been proposed. © 2006 American Institute of Physics;
