Abstract

Bismuth Ferrites (BFO), a multiferroic nanomaterial that possesses antiferromagnetic ordering above room temperature, has been the focus of material researchers for quite some time. Because the scope of its practical uses are caught up by its low magnetization due to its G-type antiferromagnetic nature below Neel temperature. Such coexistence of magnetic behaviour along with its ferroelectric property, has drawn deeper interest into its structure. It has been observed that doping with different elements and at different sites or co-doping has a significant influence on structural modification. These structural changes give different magnetic properties enabling BFOs for suitable applications. Furthermore, the synthesis process and other intrinsic characteristics also have an influence on modifications observed in magnetic behaviour, as seen for various reported results. Therefore, a consolidation of some of the remarkable changes in magnetic properties resulting from the structural changes using dopants, doping types and synthesis methods BFOs so far is reviewed here and presented in brief.

不同掺杂铋铁氧体多铁材料的结构和磁性研究进展

铋铁氧体（BFO）是一种在室温以上具有反铁磁有序性的多铁性纳米材料，长期以来一直是材料研究者关注的焦点。由于其在尼尔温度以下的G型反铁磁性质，其实际应用范围被其低磁化强度所覆盖。这种磁性行为与其铁电性质的共存，引起了人们对其结构的更深兴趣。已经观察到，用不同元素和在不同位置掺杂或共掺杂对结构改性具有显著影响。这些结构变化赋予了不同的磁性，使BFO能够用于合适的应用。此外，合成过程和其他固有特性也对磁性行为中观察到的修饰有影响，如各种报道的结果所示。因此，本文对迄今为止使用掺杂剂、掺杂类型和合成方法的BFO的结构变化所导致的磁性能的一些显著变化进行了综述并简要介绍。

期刊介绍： Crystallography Reviews publishes English language reviews on topics in crystallography and crystal growth, covering all theoretical and applied aspects of biological, chemical, industrial, mineralogical and physical crystallography. The intended readership is the crystallographic community at large, as well as scientists working in related fields of interest. It is hoped that the articles will be accessible to all these, and not just specialists in each topic. Full reviews are typically 20 to 80 journal pages long with hundreds of references and the journal also welcomes shorter topical, book, historical, evaluation, biographical, data and key issues reviews.
