摘　　要：磁性样品的表征一直是透射电镜测试领域的难题。基于国内13家公共电镜平台调研结果,参考国内外文献,提出了透射电镜表征磁性样品的前处理技术路线。同时,建立便携式永磁铁与电磁铁相结合的磁性判定方法,根据分类结果优选制样方式和测试项目。该技术路线为磁性材料的透射电镜显微分析提供了一种思路,最大限度地保护电镜不受磁性样品污染。The characterization of magnetic samples is a challenge in transmission electron microscopy tests.Based on sufficient surveys of 13 relevant institutes,and an extensive review of domestic and international literature,this paper investigates pre-processing methods for TEM characterization of magnetic samples and summarizes a technical roadmap,aiming to achieve high-quality and scientifically sound testing of magnetic samples.This technical roadmap not only provides new insights into the microscopic analysis of magnetic materials,but also maximizes the protection of the electron microscope from contamination by magnetic samples.
