Abstract

Bi0.75Ba0.25(Fe,Ti)1-xMnxO3 with x=0, 3 and 5 mol% Mn ceramics were prepared by a solid state reaction method. The relationships between site substitution of Mn in Mn-doped 0.75BF-0.25BT ceramics, phase formation and their properties were investigated. The addition of Mn was shown to improve densification, electrical and magnetic properties, especially ME coefficient. The Synchrotron X-Ray Absorption Near Edge Structure (XANES) spectra showed that Mn substituted for Fe/Ti atom and did not affect the oxidation state of Ti and Bi. However, a significant change of oxidation state was observed in Fe, Mn and Ba atoms.
