Reinterpretation of Wavelength-Modulated Absorption in SrTiO3 without Coexisting Phases
In a recently reported measurement of the wavelength-modulated absorption of SrTiO3, the results were interpreted as evidence for the coexistence of two phases over a temperature range of 60 K about the 105-K phase transition. We refute that interpretation by proposing an alternative which is necessary and sufficient to be fully consistent with the known properties of SrTiO3 and which is unconnected with the phase transition. We also propose an experimental test of the validity of this new interpretation.
