Crystallographic axis of a magnetic domain found in iron crystals has been revealed to be [100] by means of electron interference. An empirical formula for the magnetic analysis was proposed which permitted to treat quantitatively the experimental results obtained. It was necessary for carrying out the magnetic analysis by electron diffraction to utilize an electron beam of rather high energy, i.e. accelerated with about 200 kV. Representation of Ewald's reciprocal lattice was applicable suitably to the magnetic analysis of ferromagnetics in terms of electron interference.
