Patent abstract
Chirality distribution in the molecular structure of protein or the like and magnetic domain structure are analyzed with high resolution less than 10 nm. A transmission electron microscope equipped with a spin-polarized electron source is used for holography observation. The phase of transmission spin-polarized electrons changes due to the existence of chirality structure or magnetization in a sample, which is observed as an interference pattern phase shift in holography measurement.
