We have investigated dielectric properties in a series of crystals of RMnO 3 (R is a rare-earth ion) under magnetic fields and quasihydrostatic pressure. We have found that a ferroelectric phase appeared in GdMnO 3 crystal below 13 K. We have confirmed that a small spontaneous polarization exists al
