Effects of parallel and perpendicular compressive stresses on the dielectric and ferroelectric properties of soft PZT ceramics
Effects of compressive stress on the dielectric and ferroelectric properties of commercial soft PZT ceramics were investigated. The dielectric and ferroelectric properties were measured under compressive stress applied parallel and perpendicular to an electric field direction. The results showed tha...
