The effect of poling and depoling on the dielectric and piezoelectric properties of relaxor ferroelectric solid solution single crystal of 24Pb(In1/2Nb1/2)O3 -46Pb(Mg1/3Nb2/3)O3 -30PbTiO3

Abstract

The dielectric property and domain structures of relaxor 24Pb(In <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1/2</inf> Nb <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1/2</inf> )O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> - 46Pb(Mg <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1/3</inf> Nb <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2/3</inf> )O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> -30PbTiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> 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 µm width to orthorhombic domains of ∼ 20µm width with rectangular cells in size of a few µm, characterized with antiferroelectic double hysteresis loop in electric field-induced strain behavior was found.
