Structural, morphological and thermal analysis of pure and doped (Ho/Nd)-BFO multiferroics

Abstract

Pure BiFeO3(BFO) and 20% doped BFO with Holmium (Ho) and Neodymium (Nd) separately (Ho-BFO and Nd-BFO) samples are synthesized using solid state reaction method. Structural characterization is carried out using XRD and FTIR analysis. Further morphological study is performed to assist the structural analysis. In addition to these, thermal analyses such as tg-DTA comparisons are also presented here. These studies provide the understanding of impact of doping in modifying structure and related inherent properties of BFO multiferroics which are normally associated with their tuned electric and magnetic properties.

Piezo-responsive bismuth ferrite nanoparticle-mediated catalytic degradation of rhodamine B and pathogenicE. coliin aqueous medium and its extraction using external magnetic stimulation after successful treatment

“…2(c) depicts a strong absorption maximum between 400-600 cm −1 , which can be attributed to the Fe-O stretching and bending vibrations, confirming the presence of octahedral FeO 6 groups. 28 The formation of perovskite structure was further confirmed by the vibrations between 650-850 cm −1 (Fe-O) of the BFO nanoparticles. 29 The three bands at 1385 cm −1 , 1734 cm −1 , and 2362 cm −1 are attributed to O-H bending and O-H stretching, respectively.…”

“…The FTIR bands of the pure bismuth ferrite NPs are depicted in the supplementary section ( Supplementary Figure S1 ). ( Biasotto and Simões, 2011 ; Gokul et al, 2021 ) The intense vibrational bands correspond to chitosan biopolymer at 1,016 as a result of the C-O stretching. The vibrational band at 1,149 cm −1 is for the C-O-C asymmetric vibrations.…”
