Abstract
Magnetic domain structures of barium ferrite particles are studied by electron holography. Single magnetic-domain particles have been observed directly and clearly for the first time. Furthermore, an on-line real-time electron holography system has been developed for dynamic observation. Using the system, magnetic domain-walls in a thin permalloy film have been observed in real-time. Dynamic behavior of magnetic domain-walls in the magnetization or demagnetization processes is clearly observed.
