Modifications in the rhombohedral degree of distortion and magnetic properties of Ba-doped BiFeO3 as a function of synthesis methodology

Combined structural, electrical, magnetic and optical characterization of bismuth ferrite nanoparticles synthesized by auto-combustion route

“…Traces of some very low intensity peaks corresponding to secondary phases like Bi 2 Fe 4 O 9 , Bi 25 FeO 39 , etc. were identified [22]. But, overall there had been a good control over the non-perovskite phases which confirms the phase purity of BFO nanoparticles.…”

“…Various low temperature wet chemical methods, like hydrothermal, co-precipitation, micro-emulsion technique, modified Pechini's method, mechanochemical, sol-gel and solution combustion route, have been reported for the synthesis of BFO nanoparticles/ceramics [17][18][19][20][21][22] auto-combustion route but it is rare to find collective studies for structural, electrical, magnetic and optical properties of BFO nanoparticles [23][24][25]. It is known that the phase purity is needed for obtaining better magneto-electric properties of BFO.…”

Structural and multiferroic properties of nanostructured barium doped Bismuth Ferrite

“…iii) It is expected to suppress the cycloid spin structure [30]. The small particle sizes observed in the samples of the order of 30 nm are excellent for efficient ferromagnetic properties, due to the magnetic cycloid spin structure of 62 nm in this material [31]. The maximum remnant magnetization Mr and saturation magnetization Ms were found for x = 0.25 mol% with particle size 29 nm as listed in Table 2.…”

Study the influence of Nd and Co/Cr co-substitutions on structural, electrical and magnetic properties of BiFeO 3 nanoparticles

“…Previously, it has also been reported for a structural transformation from rhombohedral polar phase (SG: R3c, #161) to orthorhombic non-polar phase (SG: Pbnm, #62) with an intermediate anti-polar phase (SG: Pbam, #55) on substituting Nd ion at the Bi-site in BFO [29]. The Goldschmidt's tolerance factor (t = (r A + r O )/¥2(r B + r O )), which is one for cubic phase, determines the degree of distortion of BO 6 octahedra and stability of the phase of ABO 3 -type perovskite structure [34,35]. For smaller A-site dopants (Nd 3+ ), the value of 't' decreases, and thus distortion increases and less symmetric orthorhombic phase is preferred.…”
