The Effect of Poling and Depoling on the Dielectric and Piezoelectric Properties of Relaxor Ferroelectric Solid Solution Single Crystal of 24Pb(In_(1/2)Nb_(1/2))O_(3)-46Pb(Mg_(1/3)Nb_(2/3))O_(3)-30PbTiO_(3)

摘要

The dielectric property and domain structures of relaxor 24Pb(In_(1/2)Nb_(1/2))O_(3)- 46Pb(Mg_(1/3)Nb_(2/3))O_(3)-30PbTiO_(3) were studied by dielectric spectroscopy, polarized light microscopy (PLM) and piezoresponse force microscopy (PFM). Remarkable differences between heating and cooling run in permittivity vs. T curve and domain structures for poled specimen were found. The change in domain structures with poling from rhombohedral spindle-like domains with a few (mu)m width to orthorhombic domains of approx20 (mu)m width with rectangular cells in size of a few (mu)m, characterized with antiferroelectic double hysteresis loop in electric field-induced strain behavior was found.
