We have performed powder neutron diffraction measurements on the solid solutions of SrRu1-x-MnxO3, and found that the itinerant ferromagnetic order observed in pure SrRuO3 changes into the C-type antiferromagnetic (AF) order with nearly localized d electrons in the intermediate Mn concentration range between x = 0.4 and 0.6. With increasing x, the AF moment is strongly enhanced from 1.1 μB (x = 0.4) to 2.6 μB (x = 0.6), which is accompanied by the elongation of the tetragonal c/a ratio. These results suggest that the substitution of Mn for Ru suppresses the itinerant characteristic of the d electrons, and induces the superexchange interaction through the compression in the c plane. We have also found that the magnetic and transport properties observed in our tetragonal samples are similar to those of recently reported orthorhombic ones.
