abstract In order to distinguish the fabricated lanthanum doped bismuth-nickel ferrite perovskite oxide material (Bi1.7La0.3Ni2Fe2O8) as a competitive ferroelectric component, the material's ferroelectric and electrical properties were investigated. Complex impedance spectroscopy, electric modulus spectroscopy, P-E hysteresis loop measurement, capacitance-temperature measurement, FTIR absorption spectroscopy and UV-Visible spectroscopy were carried out to delineate its multifunctional properties. This La substituted material is characterized by excellent frequency-temperature stability, a semiconducting nature, non-Debye thermal relaxation, ferroelectric property (polarization 0.4μC/cm2), temperature dependent capacitance maximum sensitivity (58.7nF/℃) and a stable optical band gap (~3.32 eV), which are the major attributes of this ceramic to substantiate it as a promising ferroelectric entity for advanced technological applications.
