Influences of perpendicular compressive stress on the dielectric and ferroelectric properties of electrostrictive and piezoelectric Pb (Mg1/3 Nb2/3) O3 -PbTiO3 ceramics
The dielectric and ferroelectric properties of (1-x) Pb (Mg1/3 Nb2/3) O3 - (x) PbTiO3 or (1-x) PMN- (x) PT (x=0.1-0.4) ceramics were measured under compressive stress applied perpendicular to the electric field. For the dielectric properties, the experimental results revealed that the superimposed p...
