Dielectric and magnetic properties of (Pb, Ti) co-doped BiFeO3 multiferroic ceramics

In this study, Bi0.9Pb0.1Fe1-xTixO3 (0.05 ≤ x ≤ 0.20) multiferroic ceramics were prepared through solid-state reaction. The influence of Pb, Ti partial substitutions on the dielectric and magnetic properties of BiFeO3 multiferroic ceramics was investigated and discussed in detail. X-ray diffractions confirm rhombohedral perovskite phase formation (R3c space group). Scanning electron microscopy (SEM) was employed to investigate the morphology, revealing a cuboidal microstructure with bimodal distribution of grain sizes. Magnetic studies were carried out and the results reveal a slight enhancement of saturation magnetization with Ti concentration increasing. The present data indicates that Bi0.9Pb0.1Fe1-xTixO3 can be used as multifunctional material in different magnetoelectric applications.
