In the Figure of the article by Shebanova and Lazor we can see Raman spectra of a single crystal of magnetite, obtained in the case of a stepwise increase in laser power. As in the case of our Figure , for the laser power of 10 mW, we can observe the peaks at 190.5 (very weak), 301 (weak), 534 and 663.5 (strong) (cm -1 ). "New features in the spectra begin to appear when the power is increased above 20 mW. … Concurrently, the intensities of the Raman bands of magnetite gradually vanish. Analysis of the spectrum of the final reaction product shows that magnetite, subjected to increased laser power in the course of the Raman experiment conducted in air, was oxidized to the trivalent iron oxide hematite (α-Fe2O3)" .
