Enhanced ferroelectric order in Pb(Mg1/3Nb2/3)0.9Ti0.1O3 ceramics by ZnO modification
In this research, the effects of ZnO modification on ferroelectric order of Pb (Mg1/3Nb2/3)0.9Ti0.1O3 (PMNT) ceramics were studied through characterizations of dielectric and ferroelectric properties. The PMNT/xZnO (where x = 0, 0.4, 2.0, 4.0 and 11.0 mol.%) ceramics were prepared by solid state rea...
