Abstract EN
Lead-free Bi0.5(Na0.8K0.2)0.5TiO3 (abbreviated as BNKT) films have been synthesized via a sol-gel technique on Pt/Ti/SiO2/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 (Pr) and maximum (Pm) polarization reached their highest values of 9.2 µC/cm2 and 30.6 µC/cm2, respectively.
All the films showed a weak ferromagnetic behavior with the maximum saturated magnetization (Ms) of 2.1 emu/cm3.
These values are equivalent to the highest Pr and Pm values in previous reports on lead-free films.
