Abstract

The magneto-optic indicator film (MOIF) technique was used to image the magnetic domain structure in a Tb40Fe60/Fe50Co50 multilayer as either a stress or a perpendicular magnetic field was applied to the material. These observations showed that the domains did move under application of the stress, and recovered upon removal of that stress. However, the domain motion under field application was observed to be quite different, and the magnetic state was found to have been changed upon removal of the field contrary to expectations. In both cases, both inhomogeneous and homogeneous rotations were observed.
