一种变形的弹道电子发射显微镜已经发展到图像的磁性结构的薄膜多层膜与纳米分辨率。在名义上不耦合的Co/Cu/Co三层膜的研究中，磁畴和畴壁运动很容易观察到这种技术。在Co/Cu/Co三层系统磁畴被发现发生在一个类似的500 nm的长度尺度和更少，而较小规模的波动，在弹道电子输运性能的系统被发现在一个类似的10 nm的长度尺度。(C)1999年美国物理学会。[S0003-6951（99）03933-9]。
A variation of ballistic electron emission microscopy has been developed to image magnetic structure in thin-film multilayers with nanometer resolution. In studies of nominally uncoupled Co/Cu/Co trilayer films, magnetic domains and domain-wall motion are readily observable with this technique. In the Co/Cu/Co trilayer system magnetic domains are found to occur on an similar to 500-nm-length scale and less, while smaller-scale fluctuations in the ballistic electron transport properties of the system are found on an similar to 10 nm length scale.
