Study of structural and dielectric properties of Mn doped Bi0.90Pr0.10FeO3 ceramics

Multiferroics with composition Bi0.9Pr0.1Fe1-xMnxO3 (x=0.15, 0.20). has been synthesized by solid-state reaction technique. Rietveld analysis of the XRD patterns revealed that both the samples have rhombohedral crystal structure (R3c). Distortion in the lattice is observed due to mismatch of B-site ions radii. Dielectric constant and tanδ decrease rapidly with frequency showing dispersion behavior at low frequency.
