摘要:
多铁性铋铁氧体(BiFeO3)纳米粉体已在室温下通过机械合成制得。根据合成后处理方式的不同,这些纳米粉体在平均尺寸、非晶层和/或第二相的存在方面表现出差异。对新鲜、退火及热压纳米粉体进行的扩展磁性研究表明,所制备的原始粉体磁性能有显著提升。
英文摘要:
Multiferroic bismuth ferrite (BiFeO3) nanopowders have been obtained in room temperature by mechanical synthesis. Depending on the post-synthesis processing the nanopowders have exhibited differences in the mean sizes, presence of amorphous layer and/or secondary phases. Extended magnetic study performed for fresh, annealed and hot-pressed nanopowders have revealed substantial improvement of the magnetic properties in the as-prepared powder.
