Abstract :
We prepared BaTiO3/BiFeO3/BaTiO3 sandwich structural film by sol-gel process. Antiferroelectric hysteresis loop was observed in the sandwich structural film. A Monte Carlo simulation based on Ising model using a 100×100 polarization grid is carried out. Simulating result matches to the experimental result very well and it shows that the antiferroelectricity is originated from the antiferroelectric couple between the different ferroelectric layers.
