Method for producing multiple magnetic layers of materials with known thickness and composition using a one-step electrodeposition process
Abstract:
A method for multi-layer electrodeposition in a single bath is also provided. A substrate is immersed in a bath. An electrodeposition operation is initiated for depositing a first layer of material on the substrate. The electrodeposition operation includes agitating the bath and applying current pulses. The electrodeposition operation is later altered for depositing a second layer of material on the first layer, where the second layer is of a different composition than the first layer. In the altered mode, the current density is changed for altering a composition of material deposited on the substrate, the duration and/or frequency of the current pulses are altered, and the bath is agitated at a different rate of agitation.
