摘要

结果表明，在铌酸锶钡(SBN: 61)晶体中引入铥杂质会导致介电常数值的增加和相变模糊区。外场极化在一定程度上稳定了样品的极性状态，然而，极化在研究样品厚度上的非均匀分布表明存在具有高掺杂晶体特征的发达畴结构的区域。关键词:铁电体，弛豫器，热释电效应，极化分布，单晶，SBN

Influence of thulium impurity on dielectric and pyroelectric properties of single crystals of Barium Strontium Niobate

It has been shown that the introduction of thulium impurity into the crystals of strontium barium (SBN : 61) niobate leads to an increase in the dielectric constant value and the blur region of the phase transition. External field polarization partially stabilizes the polar state of the samples, however, the heterogeneous distribution of polarization across the thickness of the studied samples indicates the existence of regions with a developed domain structure characteristic of highly doped crystals. Keywords: Ferroelectrics, relaxors, pyroelectric effect, polarization distribution, single crystal, SBN.
