A ferroelectric material includes a compound of formula (I): (Pb.sub.1-x-zBa.sub.zA.sub.x)(B.sub.yZr.sub.1-y)O.sub.3, (I) wherein 0.ltoreq.x.ltoreq.0.1, 0.ltoreq.y.ltoreq.0.020, 0.15.ltoreq.z.ltoreq.0.35, with the proviso that y.noteq.0 when x=0, and that x.noteq.0, when y=0; and wherein A is a first element having a valence number greater than that of Pb, and B is a second element having a valence number greater than that of Zr. A ferroelectric memory device made from the ferroelectric material is also disclosed. |
