Abstract Laminated, exchange-insulated Permalloy layers have been proposed to reduce magnetization noise in recording heads because in these systems closure domains are replaced by a narrow edge structure, the edge-curling wall . The reaction and switching of this edge pattern in an external field was studied both theoretically and experimentally with a high resolution Kerr-microscope. We observed transitions within the edge-curling wall and interactions of these transitions with ordinary 180… CONTINUE READING
