AB  - Sr4Ru2O9 has a P62C space group and differs from the Ruddelsden-Popper series of the strontium ruthenate family where Ru is distinctly present in Ru+5 state with no Jahn-Teller activity. A significant increase in magnetic moment and coercivity is observed along with lowering of resistivity, especially around a critical concentration of x=0.2 in Sr4-xLaxRu2-xMnxO9. Such an unusual effect is correlated to the mixed magnetic pair effect arising out from the variable oxidation states of Ru as suggested by x-ray photoelectron spectroscopic studies. Our results substantiate the long-range ferromagnetism observed for Ruthenium-substituted three-dimensional manganites. (c) 2005 American Institute of Physics.
