Abstract :
This paper will present an initial evaluation of the lead zirconate-lead zinc niobate solid solution for use in nonvolatile ferroelectric memory devices. Previous work has shown that the (x)·PbZrO3-(1-x)·Pb(Zn1/3Nb2/3 )O3 [PZZN] system has “square” hysteresis loops accompanied by large remnant polarizations. In particular, compositions near the room temperature antiferroelectric to ferroelectric phase boundary will be investigated
