摘要

强调了用二价离子掺杂的BiFeO3陶瓷代替纯BiFeO3与其他铁电材料形成固溶体的重要性。(1-y)Bi0.90Ca0.10FeO3-(y)PbTiO3体系在整个组成范围内的相稳定性显示出有趣的结构调制。晶胞的变化似乎对微观结构也有显著的影响。扫描电镜研究表明，在该体系中形成了多种类型的颗粒。发现这种一种晶粒的共存在介电和磁性上都表现出弛豫型特征。用合适的模型解释了观测到的双松弛型特征的起源。低温交流磁研究表明，在0.30 <的样品中，主要的自旋玻璃型特征趋于稳定;y & lt;0.50.

Structure–property correlation in (1-y)Bi0.9Ca0.1FeO3-(y)PbTiO3 (0.0 < y < 1.0) solid solutions

The importance of using divalent ion doped BiFeO₃ ceramics in-place of pure BiFeO₃ informing solid solutions with other ferroelectric materials is emphasized. The phase stability for the (1-y)Bi_0.90Ca_0.10FeO₃-(y)PbTiO₃ system in the complete composition range show occurrence of interesting structure modulations. The changes in the crystal unit cell also seem to have significant effects on the microscopic structure. The SEM studies indicate the formation of more than one type of grains in the system. Such coexistence of one type of grains is found to show relaxor type characteristics both in dielectric and magnetic properties. Suitable models are used to explain the origin of the observed bi-relaxor type characteristics. The low temperature ac-magnetic studies suggest stabilization of a predominant spin-glass type characteristics in samples with 0.30 < y < 0.50.

期刊介绍： While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including: -insulating to metallic and fast ion conductivity -piezo-, ferro-, and pyro-electricity -electro- and nonlinear optical properties -feromagnetism. When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice. The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
