Phase Transitions of Pb(Mg1/3Nb2/3)O3-PbTiO3 Single Crystal with {110}cub Cut
{110}cub切型Pb(Mg1/3Nb2/3)O3-PbTiO3单晶铁电相变的研究

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.
