Efficient magnetoelectric dispersion in Ni and Co co-doped BiFeO3 multiferroics

Hydrothermal synthesis of Ce/Zr co-substituted BiFeO3: R3c-to-P4mm phase transition and enhanced room temperature ferromagnetism

“…Despite this, inherent problems of the bulk BFO such as formation of secondary phases, high leakage current, low magnetoelectric (ME) coupling, zero macroscopic remnant magnetization (Mr) have been restricted its multifunctional applications at room temperature [4][5][6][7]. In recent years, attempts have been made to enhance reduce dielectric loss, ferroelectric properties, and leakage current, increase remnant polarization, modify its inhomogeneous-spatial spin-modulated (incommensurate) structure, and intensify magnetoelectric interaction [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. However, the comparative studies were undertaken in order to understand of the effect of co-substitution at A-and B-site on ferroelectric and magnetic properties, respectively.…”

“…However, the comparative studies were undertaken in order to understand of the effect of co-substitution at A-and B-site on ferroelectric and magnetic properties, respectively. Recent studies revealed that a strategy of co-doping of the Bi-site, and Fe-site can significantly improve the magnetic and ferroelectric properties of BFO nanoparticles, [11][12][13][14][15][16][17][18][19][20][21]. We recently reported that the A-site (Nd, Y, Gd) and B-site (Mn, Zr) co-substitution of BFO have a result to reduce the particle size to less than 62 nm which will destruct or suppress the magnetic spiral structure [6][7].…”

Efficient Charge Storage Capability of BiFeO3-Based Bi-Phase Nanocomposites

“…6 As a matter of fact, many compounds possess multiferroic characteristics but these features become significant at temperatures that are much lower than room temperature (RT), while BiFeO 3 (BFO) is the only material that exhibits multiferroic features above RT. Hence, a significant research work has been devoted to the analysis of pure as well as doped BFO; either at A-or B-sites [7][8][9][10][11][12][13][14][15] in order to address the issues related to pure BFO. Naturally, it crystallizes as rhombohedrally distorted perovskite shape with space group R3c, whereas it can also exist occasionally in hexagonal crystalline form, having a and c lattice parameters as 5.58 and 13.90 Å, respectively.…”
