“…Besides these, there have been some reports in this regard to investigate the multiple properties. For example, the doping of V 5+ and La 3+ in the BFO sample enhanced the structural, microstructural, optical, and dielectric properties, − while very few reports show the modified magnetic properties in the framework. − Many researchers reported that the phase transition and miniaturization of leaking currents also occur in the BFO sample due to doping of (La, Pr) and (La, Sm), which further stabilizes the magnetic properties. , The rare-earth metals, e.g., Gd, play a key role in increasing the magnetization behaviors. , It is very interesting to studies the effect of A-site doping of La or Gd cations, which may affect the optical, dielectric, and magnetic properties. , …”
