- Abstract
This work presents an elaborate study of the effect in the structural and magnetic of BiFe 1 − x Zn x O 3 (x = 0 , 0.05, 0.10, 0.15, 0.20, 0.25) multiferroic materials, synthesized via a sol-gel auto-combustion method. The synthesized materials are found to have structural distortion in the rhombohedral R3c structure as observed by X-ray diffraction (XRD). Other diffraction peaks were attributed to the second phase Bi 2 5 FeO 4 0 . The Mossbauer spectra (MS) of BiFe 1 − x Zn x O 3 (x = 0 , 0.05, 0.10, 0.15) are fitted with a sextet and a doublet, and the presence of doublet also indicates the Bi 2 5 FeO 4 0 phase. The results from XRD and MS both show that Zn-substituted BiFeO3 suffers adverse effects on the formation of pure BiFeO3. BiFe 1 − x Zn x O 3 (x = 0. 2 0 , 0.25) are fitted with only one paramagnetic doublet. The absence of sextet means that there is a magnetic destruction of samples on account of a thorough phase transition from a magnetic phase to a non-magnetic phase and/or successful ion substitution (iron ions were replaced with zinc ions).
