Comparisons of polarization switching in "hard," "soft," and relaxor ferroelectrics

Abstract

The dynamics of polarization switching have been investigated over extremely broad time (10(-8)<t<10(2) s) and field ranges for hard, soft, and relaxor ferroelectrics based on aliovalent modified Pb(Zr1-xTix)O-3. The results unambiguously demonstrate important differences in the polarization switching mechanism for these various types of ferroelectrics. (C) 2004 American Institute of Physics.
