Key Points

To highlight errors in the structural analysis of BiFeO3 solid solutions reported by S. Sen et al.
Analysis of structural data presented by authors
Comparison of diffraction patterns with known samples
Errors in representing structural data for (BiFeO3)0.80(MgTiO3)0.20
Differences noted between presented numerical data and actual samples
Observations indicate the diffraction pattern aligns with BiMg0.5Ti0.5O3

Abstract

My comments concern the important error in the structure analysis of the studied sample. The presented structural data do not correspond to (BiFeO 3 ) 0.80 (MgTiO 3 ) 0.20 , as supposed by authors. The numerical data are copied from BiFe 0.75 Mn 0.25 O 3 but the diffraction pattern is similar to BiMg 0.5 Ti 0.5 O 3 crystal.
