Abstract

Abstract Bi0.8Gd0.2Fe0.95Ti0.05O3 (BGFT) multiferroic ceramics were prepared by a solid-state reaction, and their sintering, microstructure, dielectric and magnetic properties were studied. Experimental results show that BGFT ceramics sintered at 980 °C possess a pure orthorhombic (space group, Pnma) structure, and these ceramics possess high relative theoretical density (∼95%), low leakage current density (10−6 A/cm2). The magnetic and electric measurements show the coexistence of ferroelectric and weak ferromagnetic in BGFT ceramics. The results of the Rietveld refinement for BGFT ceramics reveal the existence of bismuth and oxygen vacancies, and these vacancies have an important influence on the electric and magnetic properties.
Gd和Ti共掺BiFeO3的Rietveld细化和多铁性
摘要:采用固相反应法制备了Bi0.8Gd0.2Fe0.95Ti0.05O3 (BGFT)多铁陶瓷,对其烧结、微观结构、介电性能和磁性能进行了研究。实验结果表明,在980℃下烧结的BGFT陶瓷具有纯正交(空间群,Pnma)结构,具有较高的相对理论密度(~ 95%)和较低的漏电流密度(10−6 a /cm2)。磁学和电学测量表明,BGFT陶瓷中存在铁电和弱铁磁共存现象。BGFT陶瓷的Rietveld细化结果揭示了铋和氧空位的存在,这些空位对BGFT陶瓷的电、磁性能有重要影响。

期刊介绍: Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
