Electron holography is a leading-edge technology utilizing the interference effects of electron waves and is capable of observing electromagnetic fields on the nanometer scale. By measuring electromagnetic field changes in and around specimens under the application of electric and/or magnetic fields, correspondences to their electric and magnetic properties are studied. Furthermore, visualization of collective motions of secondary electrons due to electron movement is realized by measuring perturbed electric fields. Improvement of resolution and precision of these observation technologies will enable us to clarify mechanisms of emergent matter phenomena in many-body systems with multiple degrees of freedom.
