Structural, dielectric and impedance analysis of Nd-doped BiFeO3 prepared using solid-state synthesis method

Neodymium doped Bismuth Ferrite (Nd-BFO) samples, synthesized using solid-state reaction route are subjected to various structural and dielectric characterization to investigate the influence of Nd3+ ions in modifying bismuth ferrite multiferroic properties. Structural characterizations including XRD, FESEM, FTIR, and Raman characterization have shown that higher amount of dopant concentration has caused disruption in the structural ordering. Dielectric studies such as dielectric constant, loss, measured using an LCR meter with respect to the temperature and frequency variations are analyzed in this paper. Further electrical characterization such as impedance analysis is also presented. All these results broadly indicate the tunable electrical nature of these samples at different temperatures and frequencies, with doping, which is a correlation to their structural and morphological ordering and low concentration doped Nd-BFOs only possess the potential for applications.
