  • Abstract
    The transition from twin walls to superimposed walls and vice-versa, in two-layer laminated Permalloy films has been observed. Pictures of walls and quasiwalls have been taken using the high-resolution Kerr effect. The transition occurs at reproducible values of magnetic field applied in the hard direction of the sample, and experimental results indicate that it takes place due to the motion of Bloch lines along the walls
