Abstract

The low temperature behaviour of Rb₃H(SO₄)₂ and Rb₃D(SO₄)₂ and their doped analogues was investigated by means of their dielectric response. Electron paramagnetic resonance was used to control the impurity concentration. Influence of different admixtures on ferroic properties is discussed. It has been shown that an appropriately chosen impurity in doped Rb₃H(SO₄)₂ can lead to a short-range ordering similar to that observed for doped incipient ferroelectric-like SrTiO₃ and KTaO₃.

摘要

通过介电响应研究了 Rb₃H(SO₄)₂ 和 Rb₃D(SO₄)₂ 及其掺杂类似物的低温行为。电子顺磁共振用于控制杂质浓度。讨论了不同掺杂剂对铁电性质的影响。结果表明，在掺杂的 Rb₃H(SO₄)₂ 中适当选择杂质可以导致类似于掺杂初始类铁电 SrTiO₃ 和 KTaO₃ 中观察到的短程有序。
