摘要

本文将初步评估锆酸铅-铌酸铅锌固溶体在非易失性铁电存储器件中的应用。前人的研究表明，(x)/spl middot/PbZrO/sub 3/-(1-x)/spl middot/Pb(Zn/sub 1/3/Nb/sub 2/3/)O/sub 3/ [PZZN]体系具有“方形”磁滞回线，并伴有较大的残余极化。特别地，在室温反铁电到铁电相边界附近的成分将被研究。

An evaluation of lead-zirconate based ceramics for use in nonvolatile ferroelectric memory devices

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)/spl middot/PbZrO/sub 3/-(1-x)/spl middot/Pb(Zn/sub 1/3/Nb/sub 2/3/)O/sub 3/ [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.
