Abstract

Lead-free (1-x)Bi0.5Na0.4K0.2TiO3-xBiFeO3 (abbreviated as BNKT-xBFO) ferroelectric films with x in the range from 0.00 to 0.10, were synthesized by the chemical solution deposition technique on Pt/Ti/SiO2/Si substrates. The microstructures and magnetic behaviors of BNKT-xBFO films were analyzed in detail as a function of BFO concentration. X-ray diffraction patterns indicated that BNKT-xBFO films were grown with a single-phase perovskite structure. The pure films showed an antiferromagnetic behavior. The magnetic properties of the films were gradually transferred from antiferromagnetic to ferromagnetic properties when BFO concentration was raised. The saturated magnetization (M S) reached the highest value of 10.3 emu cm-3 at the BFO-doped concentration x = 0.10. Our work will contribute to illuminate the impact of BFO (ABO3 perovskite structure) on the magnetic properties of BNKT materials at room temperature.
