Abstract—

Nanocrystalline BiFeO₃-based powder materials with an average crystallite size near 40 nm have been prepared by solution combustion synthesis from bismuth and iron nitrates using sucrose and tartaric acid as fuel. The materials have been characterized by X-ray diffraction, helium pycnometry, scanning electron microscopy, energy dispersive X-ray microanalysis, and Mössbauer spectroscopy. Magnetometry results demonstrate that the magnetic response of the materials varies over several orders of magnitude, depending on the synthesis procedure.

溶液燃烧合成纳米BiFeO 3基纳米材料的磁性

摘要-

通过使用蔗糖和酒石酸作为燃料由铋和硝酸铁的固溶燃烧合成，制备了平均晶粒尺寸接近40nm的基于纳米晶的BiFeO ₃基粉末材料。该材料通过X射线衍射，氦比重瓶法，扫描电子显微镜，能量色散X射线显微分析和Mössbauer光谱进行了表征。磁力测定结果表明，取决于合成程序，材料的磁响应在几个数量级上变化。
