Abstract
In this paper, we have reported the effect of rare earth Nd3+ ion substitution on crystal structure, ferroelectric, electrical and magnetic behavior of morphotropic phase boundary (MPB) composition of polycrystalline ceramics 0.7Bi(1−x)NdxFeO3–0.3PbTiO3(BNFPT), where x = 0, 0.05, 0.10. Rietveld refinement of XRD profiles confirms coexistence of rhombohedralR3c and tetragonal P4mmpolymorphs forming MPB for all the compositions. We observed that the remnant polarization Pr increases with increasing Nd3+ concentration. Piezoelectric studies show gradual increase in piezoelectric coefficient (d33) from 11 to 34 pC/N with increase in Nd3+ concentration for BNFPT samples. All compositions exhibit weak ferromagnetic character. For the same composition range, the study of dielectric behavior revealed gradual decrease in Curie temperature (Tc) as we increased doping content of Nd3+.
