Abstract
Temperature and field dependences of the dielectric constants under the DC biasing fields along the [011]- and [111]-directions in the cubic coordinate in Pb(Zn1/3Nb2/3)O3–4.5%PbTiO3 were investigated. The temperature–field phase diagrams were constructed in the field range below 10 kV/cm. It was confirmed that in Pb(Zn1/3Nb2/3)O3–4.5%PbTiO3 the intermediate tetragonal phase as a ground state of the system exists even without the DC field, and the tetragonal phase disappears in the external field above 4 and 3 kV/cm along the [011]- and [111]-directions, respectively. The field-induced orthorhombic-phase in the field along the [011]-direction was also found.
