英文摘要Charge transfer and cation order degrees of freedom and magnetism have been investigated in hexagonal, 9R-type, BaRu1-xMnxO3 solid solutions for 0 Mn3+ + Ru5+ charge transfer. Cation order anomalies at x = 1/3 and 2/3 evidence some Mn/Ru clustering within trimer units. The two charge regimes give rise to distinctive magnetic behaviors. Spin freezing near 25 K is observed for samples with x < 0.4, but above x=0.5 a Neel transition increases from 125 to 270 K at x=0.9. Neutron diffraction reveals an antiferromagnetic structure with a (001/2) propagation vector and two-dimensional critical behavior for the x=0.8 material.
