摘要：

The electric-field induced polarization (P-E) and strain (epsilon-E) characteristics of <110>(c)-oriented 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) crystals have been investigated, under both unipolar and bipolar drive. A field-induced transformation was observed below saturation. Under unipolar drive, the P-E and epsilon-E loops were anhysteretic even at the transformation point, demonstrating complete reversibility between ferroelectric rhombohedral and orthorhombic phases. The results show that "polarization rotation" can occur between <111>(c) and <110>(c), where the polarization is confined to the (100)(c) in a monoclinic M-b type symmetry.
