Structural Microstructural and Electrical Transport Studies of Ba(Fe0.25Eu0.25Nb0.5)O3

The complex multifunctional ceramic Ba(Fe0.25Eu0.25Nb0.5)O3 (BFEN) has been synthesized. The structural studies show two iso-structured phases related with BFN and BEN co-exists in the compound. The high dielectric constant and low dielectric loss of the compound below 575 K promises industrial applications. The activation energies obtained from the Arrhenius analysis of dc conductivity supports possible ferroelectric transition at elevated temperatures. Thus the desirable properties of two different compounds viz. multiferroic properties of BFN and high quality factor of BEN are successfully incorporated in a single compound.
