Abstract

Lead-free Bi _0.5 (Na _0.8 K _0.2 ) _0.5 TiO ₃ (abbreviated as BNKT) films have been synthesized via a sol-gel technique on Pt/Ti/SiO ₂ /Si substrates, and the dependence of the physical properties in BNKT films were investigated as a function of the crystallization temperature. The BNKT films were annealed at different temperatures (600, 650, 700, and 750°C) for 60 min in the air. The results of this study showed that the optimal crystallization temperature is 700°C. At this, the BNKT films exhibited a single perovskite phase structure and high-dense surface. Besides, the remanent (P _r ) and maximum (P _m ) polarization reached their highest values of 9.2 μC/cm ² and 30.6 μC/cm ² , respectively. All the films showed a weak ferromagnetic behavior with the maximum saturated magnetization (M _s ) of 2.1 emu/cm ³ . These values are equivalent to the highest P _r and P _m values in previous reports on lead-free films.
