Reversible and piezoelectric nonlinearity: The dielectric response in multicomponent solid solutions with different manifestations of the character of ferroelectric properties
Ceramics of a modified Ba multicomponent system of PbNb2/3Zn1/3O3-PbNb2/3Mg1/3O3-PbNb2/3Ni1/3O3-PbTiO3 were developed. A comprehensive study was peformed of the reversible dielectric nonlinearity and electromechanical, dielectric, and piezoelectric characteristics of the multicomponent ceramics, which have properties of relaxors, ferroelectric materials with diffused phase transitions, and classical ferroelectric material. Correlations between compounds, structures, properties, and ranges of application were established.
