Changes in ferroelectric properties of ceramics in lead magnesium niobate-lead titanate system with compressive stress
Effects of compressive stress on the ferroelectric properties of Pb (Mg1/3 Nb2/3) O3 - PbTiO3 (PMN-PT) ceramics were investigated. The ceramics with the formula (1-x) Pb (Mg1/3 Nb2/3) O3 - (x) PbTiO3 or (1-x) PMN- (x) PT (x=0.1-0.5) were prepared by a conventional mixed-oxide method. Dense perovskit...
