Recently, in Reviews of Modern Physics, I have read an erratum which represents an apology for a copied verbatim text. The text is:
“Large parts of Sec. VI.A, “Inverse magneto-optical excitation of magnetization dynamics: Theory,” consist of text
and equations that are verbatim quotes, or very nearly so, of material in the paper by Gridnev (2008). Although this theory
was developed in close collaboration with Dr. Gridnev and jointly published in Kalashnikova et al., Phys. Rev. Lett. 99,
167205 (2007) and Kalashnikova et al., Phys. Rev. B 78, 104301 (2008), we adopted the more compact and rigorous description
given in Gridnev (2008) for this review. We regret that we did not identify these parts of our review as direct quotes, and we
apologize to V. N. Gridnev and the readers of Reviews of Modern Physics for this oversight.” from here.
Although there is a copied text, from what I see, there is not a retraction. The question is: why this paper was not retracted?
