“…Doping Er 3+ at Bi‐site of BFO has onset the saturation in the ferroelectric loop . As the conduction band of BFO is related to the d‐orbital state of Fe 3+ ion, Fe site substitute ions can have a strong impact on physical properties by changing the electronic structure near the Fermi level . Therefore, doping at Fe site has boosted further the ferroelectric nature of BFO.…”

“…The earlier works on Mn doped BFO such as (Nd, Mn), (Eu, Mn), (Gd, Mn), (Ce, Mn) and (Er, Mn and Co) showed the enhancement in the ferromagnetism . Among the several investigation on dual doping of elements at Bi site and Fe site, Er doping at Bi site and transition metals such as Co, Mn and Tm at Fe site exhibited better multiferroicity .…”

“…Multiferroic material exhibits simultaneous magnetic and ferroelectric order. The resulting magnetoelectric coupling in these materials has attracted the scientific fraternity in recent years . Among the single phase multiferroic materials, rhombohedrally distorted pervoskite multiferroic BiFeO 3 (BFO) has attracted greatly as it is the only known single phase multiferroic material at room temperature.…”

“…These minor constraints faced by BFO can be circumvented by doping it with suitable elements at Bi and Fe site. Recently, investigations such as Bi–site substitutions by rare earth or alkaline earth metals and Fe site substitution by transition metals have been reported for the improvement of the BFO properties . The substitution at Bi site is expected to decrease the volatility of Bi while Fe doping can collapse the spin cycloid structure to enhance the magnetic characteristics of BFO and hence both the ferromagnetic and ferroelectric properties of BFO could be improved.…”

Single phase multiferroic undoped BiFeO 3 notoriously suffers due to the poor spincharge coupling resulting in limitations to device applications. The present work focuses on the tailoring of its multiferroic and magnetoelectric coupling properties by synthesizing multiferroic Bi 0.95 Er 0.05 Fe 0.98 TM 0.02 O 3 (TM = Nb, Mn and Mo) ceramics. The ferroelectric, magnetic, current leakage measurements and magnetoelectric effect were investigated. XRD along with the Reitveld refinement results confirms that all the samples possess perovskite based rhombohedral structure and reveals that doping of (Er, Nb), (Er, Mn) and (Er, Mo) induced the crystallographic distortion in the BFO lattice and hence induced a variation in the bond lengths and bond angle.Dual doping significantly enhanced the electrical, magnetic properties and magnetoelectric coupling as compared to BiFeO 3 . Doping has lowered the leakage current by three to four orders compared to BFO. The lattice distortion, reduced leakage current and destruction of spin-cycloidal structure could be the origin for these improved features. The (Er, Nb) doped BiFeO 3 yields enhanced ferroelectric character with the maximum polarization value of 0.46 µC/cm 2 , maximum ME coupling of 0.22 mV/ cm at a magnetic field of 130 G, an improved magnetization with a remanance value of 0.0903 emu/g and the lowest leakage current density.

“…Note that the estimated Goldschmidt tolerance factor for the co-doped samples is found to be less than 1. This indicates that the driving force for the octahedral rotation increases and consequently the Fe-O and B-O bonds may be under compression and tension strain, respectively [39][40][41].…”

Bismuth ferrite (BFO) and (Yb, Co) co-doped BFO powder are successfully synthesized using the sol-gel method. The structural, electrical, magneto-dielectric and multiferroic properties of pure and co-doped BFO have been systematically investigated. The crystal structures of these samples are investigated using x-ray diffraction techniques, which confirmed the single-phase polycrystalline rhombohedral perovskite structure with the R3c space group. The co-substitution studies revealed that the electrical, ferromagnetic and ferroelectric properties of BFO were significantly enhanced compared to pure BFO samples.
