Retraction Note: Study of effect of Gd substitution at the Fe site on structural, dielectric and electrical characteristics of BiFeO3.

Comments on the paper Study of effect of Gd substitution at the Fe site on structural, dielectric and electrical characteristics of BiFeO3 by L. Thansanga et al. (Appl. Phys. Further investigation has found that: The authenticity of the structural data in Table 1 could not be verified; The diffraction data set appears to be incomplete; The chemical formula used by authors, BiFe0.85Gd0.15O3, appears to be incorrect.
