摘要

组成Bi0.9Pr0.1Fe1-xMnxO3 (x=0.15, 0.20)的多铁材料。已通过固相反应技术合成。XRD图的Rietveld分析表明，两种样品均具有菱形晶体结构(R3c)。由于b位离子半径的不匹配，观察到晶格中的畸变。介电常数和tanδ随频率迅速降低，在低频表现出色散特性。

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.
