In the fabrication of bubble devices, the coercivity of permalloy used to move bubble domains is often a function of underlays onto which the permalloy is deposited. NiP is one such underlay. It has been found that the coercivity of permalloy on a NiP underlay will depend on the thickness of the underlay, for thicknesses up to about 800 angstroms, if the following bath is used for plating of the underlayer.
