Abstract
A method of and apparatus for providing single wall self-biased magnetic domains in a film of uniaxial magnetic material.

The material characteristics of the two films and their thicknesses are chosen such that the exchange coupling between the two films provides the effect of an external field for supporting the single wall domains.
