Abstract
Methods of forming ferromagnetic liners on the top surface and sidewalls of conductive lines of magnetic memory devices. The ferromagnetic liners increase the flux concentration of current run through the conductive lines, reducing the amount of write current needed to switch magnetic memory cells. In one embodiment, an in-bound pole is formed at the bottom edge of conductive lines, further concentrating the flux.
