Separation of Phases and Charge States in Relaxor Ferroelectric PbCo1/3Nb2/3O3

The permittivity, conductivity, electric polarization, and features of high-resolution X-ray diffraction scattering of a relaxor ferroelectric PbCo 1/3 Nb 2/3 O 3 have been investigated in the temperature range 5–350 K. Continuous correlated temperature changes in dielectric properties and electric...

Beschreibung
Zusammenfassung:	The permittivity, conductivity, electric polarization, and features of high-resolution X-ray diffraction scattering of a relaxor ferroelectric PbCo 1/3 Nb 2/3 O 3 have been investigated in the temperature range 5–350 K. Continuous correlated temperature changes in dielectric properties and electric polarization have been revealed, which were not typical of relaxor ferroelectrics. These changes can be attributed to local polar domains, which were induced in the original crystal matrix. In such domains, the charges (valences) of Co and Nb ions were continuously changed.
