We investigate the effects of Ru-doping in polycrystalline TbMn1-xRuxO3 (x≤0.10) on the multiferroicity.It is observed that the Ru substitution gradually melts away the dielectric anomaly at the ferroelectric transition point and the ferroelectricity by suppressing the polarization,accompanied with a surprising low-temperature dielectric plateau.

随着电子元件的微型化,巨介电常数材料的研究成为材料科学研究的热点之一,具有高熔点、高硬度、高耐磨性、耐氧化等优点的传统陶瓷材料仍然是研究的重点之一.早在1983 年人们就开始研究单钙钛矿陶瓷SrTiO3 介电现象,其室温介电常数达到20000[1].
