The piezoelectric properties of a Pb[(Mg(1/3)Nb(2/3))(0.68)]Ti(0.32)O(3) binary system single crystal poled along the [001] direction in the rhombohedral phase were investigated under pressures up to 400 MPa at 25 °C. For the transverse electromechanical property, the difference Δf between the resonance f(r) and antiresonance frequencies f(a), the Δf/f(r)(More)
The dielectric property and domain structures of relaxor 24Pb(In<inf>1/2</inf>Nb<inf>1/2</inf>)O<inf>3</inf>- 46Pb(Mg<inf>1/3</inf>Nb<inf>2/3</inf>)O<inf>3</inf>-30PbTiO<inf>3</inf> were studied by dielectric spectroscopy, polarized light microscopy (PLM) and piezoresponse force microscopy (PFM). Remarkable differences between heating and cooling run in(More)
The domain structures of poled and depoled lead-based relaxor ferroelectric solid-solution single-crystal 24Pb(In(1/2)Nb(1/2))O(3)-46Pb (Mg(1/3)Nb(2/3))O(3)-30PbTio(3) are studied by polarized light microscopy, piezoresponse force microscopy (PFM), scanning electron microscopy (SEM), and dielectric spectroscopy. The domain structures in the nonergodic(More)
