Abstract
Do** with different valence ions in Aurivillius compounds can induce lattice distortion and further affect the ferroelectric and magnetic properties of the materials. In this work, CaxBi6–xFe0.5Co0.5Ti4O18 thin films were prepared to study the influence of the substitution of Ca2+ for Bi3+ on the microstructure and the dielectric, ferroelectric, leakage, and magnetic properties. The results show that the lattice distortion and the internal stress are both increased with increasing Ca2+ do** level. The dielectric and ferroelectric measurements suggest that the film with a low do** concentration (x = 0.2) exhibits better performance than the films with higher do** concentrations. Although lattice distortion and valence changes in the ions have been produced, which may have affected the distortion of the A/B-O octahedral crystal structure, tests of magnetic properties demonstrate that no regular changes are caused by the Ca2+ do**.
