| 5 | POLAR NANOREGION IN RELAXOR FERROELECTRICS STUDIED BY ANALYTICAL ELECTRON MICROSCOPY显示文摘Relaxor ferroelectrics have different properties from that of the normal ferroelectrics,such as dielectric properties with diffuse phase transition and frequency dispersion,specific heat,birefringence,elastic constants and Raman scattering,etc.It is considered that the different properties are related with the polar nanoregions in relaxors.In this work we briefly introduce how we use the high spatial resolution analytical electron microscopy and high resolution electron microscopy methods to investigate the polar nanoregion in Pb(Mg_(1/3)Nb_(2/3))O_(3)(PMN),Pb(Mg_(1/3)Nb_(2/3))O_(3)PbTiO_(3)(PMNPT)and Ba(Ti_(1-x)Sn_(x))O_(3)(BTSn).The main experimental results110 are as mentioned in next three parts. | Y.L.LI L.XIE J.ZHU | 2012 | Journal of Advanced Dielectrics2012，2，2： | 0 |
