Abstract: The dielectric and piezoelectric properties, polarization vs E-field curves of Pb(Mg1/3 Nb2/3)O3-PbTi03 single crystal were measured. Results show that the ferroelectric properties strongly depend on the composition and poling field. These are essentially attributed to the intrinsic metastable orthorhombic ferroelectric state, whose phase stability depends on the composition and poling field intensively.
