Electrical properties of (Nd, Cr) co-doped Bismuth Ferrites synthesized via solid state method

Neodymium and Chromium codoped bismuth ferrite samples [Bi0.8Nd0.2Fe1-xCrxO3 (x = 0.2,0.4,0.6 and 0.8)] are prepared using solid state reaction method. Structural and morphological studies including XRD, FESEM and Raman characterization are carried out as preliminary characterizations. Dielectric studies such as dielectric constant, dielectric loss, and subsequent impedance analysis and ac conductivity measurements with respect to frequency and temperature reveal that lower concentration of dopant have stable results. The electrical properties in connection with the structural and morphological understanding of samples and the nature of dopant element and their concentration have been discussed here.
