Symmetry determination of commensurate and incommensurate phases of K2SeO4 by EPR
Description
From a reinterpretation of previously reported EPR results on γ-irradiated K2SeO4 crystals, the space group symmetry for commensurate (ferroelectric) phase of K2SeO4 is determined to be Pna21. The EPR results support the modulation of polarization as the reason for disappearance of ferroelectricity in incommensurate phase. (author)
