Abstract: A memory element for use in photoelectric data recording apparatus comprising a layered structure of a conductive substrate, ferroelectric material, discontinuous interface layer, photoconductor, and top conductive electrode. The top conductive electrode an discontinuous interface layer are chosen in conjunction with the photoconductor to act as blocking contacts in the dark and injecting contacts in the light. It is also desirable, although not essential, that the discontinuous interface layer make a blocking contact with the ferroelectric.

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.
