Growth, ferroelectric properties, and phonon modes of YMnO3 single crystal

Abstract

YMnO3 single crystals were grown by flux method and plate-like single crystals with the c-axis perpendicular to the surfaces were obtained. The maximum size of these crystals was about 2 x 2 x 0.07 mm(3). Ferroelectric properties were measured at various frequencies and abnormal behavior at the low frequencies were observed and discussed using non-linear current-voltage behavior. Raman and IR spectra were obtained, and those results were compared with previous work.
