Raman scattering experiments show that potassium dihydrogen phosphate
crystals undergo a metastable ferroelectric phase transition induced by
a static electric field at 119 K. Qualitative changes occur in the Raman
spectra of all possible scattering geometries for applied d.c. electric
field intensities of the order of 4 kV cm(-1). The phase transition is
induced by rotation of phosphate ions changing from C-2(Z) local sites
symmetries to sigma(upsilon)(YZ) sites maintaining the same factor group
C-2 upsilon. An assignment of the modes in the metastable phase is
presented. Copyright (C) 2000 John Whey & Sons, Ltd.
