Abstract: The movement of single wall domains in an internal layer of a film of magnetic material permits operation unencumbered by surface defects or interactions with substrates on which the film is formed for bias fields over a range which is large compared to the range of bias fields characteristic of films in which single wall domains extend from surface to surface.

Abstract: Poling of ferroelectric tungsten bronze-like crystalline material in which the cation sites are substantially filled is expedited by electrolysis at temperatures in excess of the ferroelectric Curie temperature for periods of the order of one hour for bodies one centimeter in length. Electrolysis is carried out in an atmosphere which will yield positive ions such as H , D and Li which migrate through the body during processing.
