Abstract

Specific features in the magnetization of BiFeO₃ nanoclusters synthesized under solution combustion conditions with a size of nearly 50 nm are described. It has been shown that the magnetic response of nanoclusters may appreciably variate, if they are synthesized with different types of organic fuel. The magnetic behavior of this material can be described by the model of noninteracting particles, when tartaric acid is used, and by the model of aggregated particles with an amorphous or fractal magnetic shell, when saccharose is used.

溶液燃烧合成的BiFeO 3纳米团簇之间相互作用的特定特征

摘要

描述了在溶液燃烧条件下合成的BiFeO ₃纳米团簇的磁化的特定特征，其尺寸接近50 nm。已经表明，如果纳米团簇是用不同类型的有机燃料合成的，它们的磁响应可能会明显变化。当使用酒石酸时，可以通过非相互作用颗粒的模型来描述这种材料的磁性能；而当使用蔗糖时，可以通过具有无定形或分形磁壳的聚集颗粒的模型来描述这种材料的磁行为。
