Retraction of: Scientific Reports https://doi.org/10.1038/s41598-021-97499-7, published online 10 September 2021


The Editors have retracted this Article.


After publication of this Article it was brought to the Editors' attention that some of the data appear to overlap with those in another article from these authors1. Specifically:

  • the TEM image of Fe3O4 nanoparticles in Figure 1 appears to be identical with the TEM image of zinc ferrite in Figure 3 in1;

  • the Fe3O4 VSM data in Figure 2B appear to be identical with the VSM data for zinc ferrite in Figure 4B in1;

  • there are unusual irregularities in the FTIR spectra shown in Figure 3.


The Authors are unable to provide the raw data underlying these experiments; the Editors therefore no longer have confidence in the results presented.


Antoine Ferreira agrees with this retraction and its wording. Fakhreddin Ashrafizadeh disagrees with this retraction.
