摘要

研究了(1-x)Ba0.99Ca0.01Zr0.02Ti0.98O3 (BCZT)-xBiFeO3 (BFO) (x = 0.00, 0.05, 0.10, 0.15)陶瓷的介电、铁电和铁磁性能。x射线衍射和拉曼数据表明，当x = 0.15的组分在1100℃下烧结时，随着BFO浓度的增加，BFO发生了四方向伪圆的相变，并形成了BFO。相应的，样品在介电常数最大值处温度较高，且频率色散较弱。令人惊讶的是，x = 0.15的组合物表现出弱铁电性和良好的磁性能，2Mr ~ 0.60 emu/g, 2Hc ~ 0.36 kOe。

Dielectric, ferroelectric and ferromagnetic properties of multiferroic (1-x)Ba0.99Ca0.01Zr0.02Ti0.98O3-xBiFeO3 ceramics

ABSTRACT Dielectric, ferroelectric and ferromagnetic properties of (1-x)Ba0.99Ca0.01Zr0.02Ti0.98O3 (BCZT)-xBiFeO3 (BFO) (x = 0.00, 0.05, 0.10, 0.15) ceramics have been investigated. X-ray diffraction and Raman data documented the tetragonal-to-pseudocubic phase transformation with increasing the concentration of BFO and the formation of BFO when the composition with x = 0.15 was sintered at 1100°C. Correspondingly, the samples showed a high temperature at permittivity maxima along with a weak frequency dispersion feature. Surprisingly, the composition with x = 0.15 exhibited weak ferroelectric and good magnetic properties with 2Mr∼0.60 emu/g, 2Hc∼0.36 kOe.

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.
