ABSTRACT:
A method of forming a serrated surface topography useful for the unidirectional propagation of magnetic domains is disclosed. The method includes the step of forming a substantially rectangular wave topograhy on the surface of the structure and subsequently ion milling the rectangular wave topography at an oblique angle of incidence to form the serrated surface topography.
