  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.
