Insights of Dielectric relaxations in Nd and Mn co-substituted BiFeO3
arXiv:1512.02757
Abstract
The composition-driven structural transition from the R3c to Pbnm symmetry was observed. Highest dielectric constant was observed for Bi0.95Nd0.05Fe0.95Mn0.05O3. Conductivity can be explained by the small polaron hopping model. The non-Debye type of dielectric relaxation is observed. The dielectric anomaly at the magnetic transition temperature is evident.
