Abstract

The permittivity, conductivity, electric polarization, and features of high-resolution X-ray diffraction scattering of a relaxor ferroelectric PbCo_1/3Nb_2/3O₃ 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.

弛豫铁电PbCo 1/3 Nb 2/3 O 3中的相和电荷态分离

摘要

研究了弛豫铁电PbCo _1/3 Nb _2/3 O ₃的介电常数，电导率，电极化和高分辨率X射线衍射散射的特征，其温度范围为5–350K。已经揭示了介电性质和电极化，这不是弛豫铁电体的典型特征。这些变化可以归因于在原始晶体基质中诱导的局部极性域。在这些区域中，Co和Nb离子的电荷（价）不断变化。
