“…Bismuth ferrite (BiFeO 3 ) has been studied intensively over the last decades. It possessing high T C (above 1000 K) and Néel Temperature ( ∼ 643 K) is both ferroelectric and antiferromagnetic at RT. ,,− It is one of the few compounds that exhibit the multiferroic at RT. It is also the typical sample that researchers choose to investigate the physics behind multiferroic couplings and corresponding devices.…”

Since the positive influences of defects on the performance of electroceramics were discovered, investigations concerning on defects and aliovalent doping routes have grown rapidly in the fields of inorganic chemistry and condensed matter physics. In this article, we summarized the types of defects in electroceramics as well as characterization tools of defects and highlighted the effects of intrinsic and extrinsic defects on the material performances with the emphasis on dielectric, ferroelectric, and piezoelectric properties. We mainly introduced defect related theoretical simulation and experimental results in several typical incipient ferroelectrics, ferroelectrics, and antiferroelectrics. Hence, the influences of defects on the crystal lattice were summed up, and then the main physical mechanisms were highlighted. Particularly, the performance enhancements of aliovalently doped electroceramics were also evaluated and reviewed. Finally, the outlook and challenges were discussed on the basis of their current developments. This article covers not only an overview of the state-of-the-art advances of defects and aliovalent doping routes in electroceramics but also the future prospects that may open another window to tune the electrical performance of electroceramics via intentionally introducing certain defects.

“…For BiFeO 3 , few donor ions with the valence of +4 or +5 can occupy the A-site. The research studies concerning the B-site donor doping in BiFeO 3 have been concentrated on Zr 4+ , , Ti 4+ , and Nb 5+ ions . Zr 4+ is found to reduce the leakage and improve ferroelectric properties of BiFeO 3 ceramics.…”
