Abstract
Abstract Usual methods of observing magnetic domain walls in transmission electron microscopy all rely on the deflection caused to the electron beam by the Lorentz force. This deflection can also alter the conditions for Bragg reflection of the electrons. In buckled specimens containing bend extinction contours, the position of the contours can be altered. This effect is particularly noticeable in cobalt, where two different types of effects have been observed. In addition to revealing the position of the domain walls when the specimen is in focus, the effect provides an interesting visible demonstration of the magnetostatic potential distribution in uniaxial thin films proposed by Malek and Kamberský (1958).
