英文摘要	用固相反应合成了Pb1-xTbxTi1-xMnxO3(0≤x≤0.10)固溶体,并用X射线粉末衍射进行了表征,室温下其空间群为P4mm.热分析仪测试结果显示,随着Tb和Mn掺杂量的增加,该固溶体的相变温度Tc降低.介电常数在Tc附近出现峰值,表明对应的相变是铁电相变.磁性测量显示,当x=0.08和x=0.10时,Pb1-xTbxTi1-xMnxO3分别在25和29 K附近有顺磁性向反铁磁性的转变.; Solid solutions of Pb1-xTbxTi1-xMnxO3 (0≤x≤0.10) were synthesized by a traditional solid state reaction and characterized by powder X-ray diffraction. The solutions crystallize in the P4mm space group at room temperature. Differential scanning calorimetry (DSC) measurements were performed to obtain phase transition temperatures (Tc) for the samples, and these were found to decrease with an increase in the amount of doped Tb and Mn. The temperature dependent dielectric constant shows a peak close to the Tc, indicating that the corresponding phase transition is a ferroelectric phase transition. Magnetic measurements Indicate that a paramagnetic to antiferromagnetic phase transition occurs at 25 and 29 K for Pb1-xTbxTi1-xMnxO3 with x=0.08 and x=0.10, respectively.; 国家自然科学基金; 北京市教委重点基金; 科技部重大研究计划项目; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000288909800036&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 4; 990-994; 27
