Pseudolinearity in the inverse dielectric susceptibility of poled Pb(Mg1/3Nb2/3)O-3-PbTiO3 crystals
For poled oriented 0.67Pb(Mg1/3Nb2/3)O-3-0.33PbTiO(3) single crystals, dielectric measurements have revealed pseudolinear (Curie-Weiss) behavior for temperatures below a phase transition; however, significant deviations are observed in the paraelectric phase. The value of the Curie constant (C) in the poled polydomain condition was found to be significantly larger than that in a poled monodomain condition. It is believed that polarization heterogeneity exists within the poled polydomain condition. (C) 2002 American Institute of Physics.
