Among the different types of multiferroic compounds, bismuth ferrite (BiFeO 3 ; BFO) stands out because it is perhaps the only one being simultaneously magnetic and strongly ferroelectric at room temperature. Therefore, in the past decade or more, extensive research has been devoted to BFO-based materials in a variety of different forms, including ceramic bulks, thin films and nanostructures. Ceramic bulk BFO and their solid solutions with other oxide perovskite compounds show excellent ferroelectric and piezoelectric properties and are thus promising candidates for lead-free ferroelectric and piezoelectric devices. BFO thin films, on the other hand, exhibit versatile structures and many intriguing properties, particularly the robust ferroelectricity, the inherent magnetoelectric coupling, and the emerging photovoltaic effects. BFO-based nanostructures are of great interest owing to their size effect-induced structural modification and enhancement in various functional behaviors, such as magnetic and photocatalytic properties.

“…Nevertheless, there is no solid evidence that the substitution can stabilize the weak ferromagnetic polar state at H = 0 [17,18]. Indeed, recent investigations indicate that the relatively high spontaneous magnetization, which could appear in the ferroelectric phase of the Bi 1−x RE x FeO 3 series, is not intrinsic and originates from the presence of ferrimagnetic impurities [19,20]. A composition-driven antiferromagneticweak ferromagnetic transformation has recently been found in the oxygen-defficient Bi 1−x Ca x FeO 3−x/2 ferroelectrics (in this system, the polar phase exists at x ⩽ 0.1 [21,22]; the materials are widely studied nowadays because of their promising potential for nanoscale technologies [23][24][25][26][27]).…”

Recognition of the factors that may significantly affect the multiferroic properties of BiFeO3-based perovskites remains one of the most challenging tasks in condensed matter physics. To reveal the reasons behind the doping-driven instability of the cycloidal antiferromagnetic order in the polar phase of Bi(1-x)Ca(x)FeO(3-x/2), synthesis and investigation of the crystal structure, microstructure, local ferroelectric and magnetic properties of the ceramic samples of Bi0.9Ca0.1Fe(1-x)Ti(x)O(3-δ) (x = 0.05, 0.1, 0.15) have been carried out. The compounds possess a rhombohedral structure (space group R3c). The compositional dependence of unit cell volume in this series can be interpreted as suggesting the doping-induced elimination of anion vacancies at x ⩽ 0.1 and the formation of cation vacancies at x > 0.1. The filling of oxygen vacancies suppresses a weak ferromagnetic contribution characteristic of the parent Bi0.9Ca0.1FeO2.95. The appearance of cation vacancies restores the weak ferromagnetic phase. The key role of lattice defects in the magnetic behavior of Ca-doped BiFeO3 has been confirmed by the observation of a correlation between the magnetic properties and the morphology/ferroelectric domain structure of the Bi0.9Ca0.1Fe(1-x)Ti(x)O(3-δ) ceramics.
