A magnetic skyrmion is a nanometer-scale vortex-like magnetic structure stabilized in magnets without spatial inversion symmetry. The magnetic skyrmions have been actively investigated for their possible applications to the next generation spintronics devices. For their practical applications, understanding their structures and their response are indispensable. Lorentz transmission electron microscopy is an effective method for observing magnetic skyrmions directly in real-space. Lorentz transmission electron microscopy has been playing an important role in research of magnetic skyrmions combined with other observation and analytical techniques of transmission electron microscope. Here, we review some researches on magnetic skyrmions by techniques of transmission electron microscopy and data analysis.
