Abstract

The composite material filled with nano-sized BaTiO3 and Fe3O4 was designed and studied. The aluminium phosphate ceramics was used as a matrix. The XRD analysis demonstrates only the crystalline structure of the fillers used. The thermogravimetric analysis proves the thermal stability of the composites up to 950 K. The Maxwell-Wagner relaxation was observed in the dielectric spectra of the investigated composites. The dielectric spectroscopy proves the close contact between the nanoparticles with the different ferroic ordering. The phosphate-based composites have been proved to be a prospective candidate for the multiphase multiferroic materials design and development.

摘要

设计并研究了填充有纳米级BaTiO3和Fe3O4的复合材料。以磷酸铝陶瓷为基体。XRD分析仅表明所使用填料的晶体结构。热重分析证明了复合材料在高达950 K时的热稳定性。在所研究复合材料的介电谱中观察到了麦克斯韦-瓦格纳弛豫现象。介电谱证明了具有不同铁电有序性的纳米颗粒之间的紧密接触。已证明基于磷酸盐的复合材料是多相多铁性材料设计与开发的潜在候选材料。
