摘要
利用电子全息显微学方法,从理论和实验两方面,系统研究了磁隧道结势垒层的内势分布,指出了一些在实验过程中应予以注意的实验现象,提出了可能的解决方法.
Electron holography was successfully used to investigate the distribution of the potential of the barrier in magnetic tunnelling junctions experimentally and theoretically. We got a clear profile of the potential which shows a ＂well＂ in reconstructed phase profile. We also pointed out some artefacts in electron holographic study of magnetic tunnelling junctions and suggested some possible methods to resolve them.
