摘要:

 利用固相反应法制备了钛掺杂的YMn1–xTixO3 (x=0.1,0.2)固溶体,对掺杂前后体系的晶格结构、磁性以及铁电性进行了研究。结果表明:掺杂后的样品仍然维持六角相结构,在x=0.2时开始有菱形 结构出现,掺杂体系保持着原有的铁电与反铁磁共存的状态,并伴随着弱铁磁性的出现;随着掺杂的增加由Curie-Weiss拟合得到的Weiss温度(负值)逐渐升高,表明反铁磁作用在减弱;体系在低温会发生自旋玻璃态转变,同时冻结温度Tf随着掺杂量的增加逐渐降低;对于体系铁电性测量表明其依然保留着原有的铁电性能,且极化强度会随着掺杂浓度的提高而增强。

 A solid solution of titanium doped YMn1–xTixO3 (x=0.1, 0.2) was prepared by a solid-state reaction method. The lattice structure, magnetic properties and ferroelectric properties of the doped system were investigated. The results show that the doped sample still maintains a hexagonal phase structure, and a rhombohedral structure appears as x=0.2. YMn1–xTixO3 has ferroelectric and antiferromagnetic behaviors as a weak ferromagnetic material. The Weiss temperature (negative value) obtained by the Curie-Weiss fitting increases gradually with the increase of doping, indicating that the antiferromagnetism is weakened. Based on the temperature variation curve and relaxation curve, the system has a spin glass transition at a low temperature, and the freezing temperature Tf decreases with the increase of doping. The ferroelectric measurement of YMn1–xTixO3 was also measured. YMn1–xTixO3 still holds the original ferroelectric properties, and the polarization strength becomes larger when the doping concentration increases.
