Synthesis, microstructure and properties of BiFeO₃-based multiferroic materials: A review

Effects of Mn doping on structural, dielectric and multiferroic properties of BiFeO3 nanoceramics

“…However, this minor tilt of anti-phase B-site Fe ions causes very weak ferromagnetism in a pure BFO sample because of the partial distortion of the spiral periodicity and presence of spin canting. As a result, the corresponding displacement of A-site Bi ions in [111] direction in the pseudo cubic axis also causes the system to be slightly non-centrosymmetric and contributing to ferroelectric polarization apart from the stereochemical activity of the lone pair of electrons of the bismuth atoms [6]. Several strategies like doping in A-or B-sites have been adopted by the researchers to improve the magnetic moment in BFO, which in turn produces large ME coupling [7].…”

Combination of structural and microstructural effects in the multiferroic response of Nd and Ti co-doped BiFeO3 bulk ceramics

“…Finally the effect of Nd 3+ and Ti 4+ co-doping in the magnetic properties of the bulk bismuth ferrite ceramics was also studied. Figure 8a first shows the room temperature magnetization curves for the BFO and the BFTO samples, whose magnetic behavior has been previously reported in the literature [5,34,46]. The parent BFO sample shows an almost-linear relationship between the magnetic field and the magnetization, the expected behavior for an antiferromagnet below T N .…”

Nanocasting synthesis of BiFeO3 nanoparticles with enhanced visible-light photocatalytic activity

“…This synthetic technique requires calcination temperatures of at least 500 °C for a minimum of 1-2 h, which can lead to particle growth, agglomeration and to the formation of secondary phases. It should be noted that, in general, low calcination temperatures favor the generation of smaller particles with narrow bandgaps and promote the formation of pure-phase BiFeO 3 materials [19,[22][23][24]34,35].…”
