    Abstract: Local cobalt concentration inhomogeneities in bubble domain devices make possible a series of device designs in which various functions are expedited. These functions include bubble generation, bubble replication, bubble positioning and various logic functions. The exemplary materials are uniaxial rare earth and related orthoferrites in which small amounts of cobalt reduce anisotropy.

    Abstract: Partial substitution of small amounts of cobalt in a class of materials, sometimes referred to as hexagonal ferrites, produces marked changes in anisotropy. This, in turn, results in an increase in domain wall mobility or in other characteristic changes of device interest. A leading class of such devices is known as ''''bubble'''' or single-wall domain devices.
