YMnO 3 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 × 2 × 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.
