Granted: 2003-07-11
Abstract: A tunnel junction (10) having a cladded read conductor formed from a high magnetic permeability soft magnetic material for a pinned-on-the-fly soft reference layer is disclosed. The tunnel junnel junction includes a data layer (11), a barrier layer (13) formed on the data layer, a cap layer (15) formed on the barrier layer, and a soft reference layer (17) formed on the cap layer. The soft reference layer (17) includes a read conductor (19) a cladding (21) that completely surrounds the read conductor (19) to form a cladded read conductor. The soft reference layer (17) has a non-pinned orientation of magnetization (M1). When an externally supplied read current flows through the read conductor, the read conductor (19) generates a magnetic field that is substantially contained within the cladding (21) and is operative to dynamically pin the orientation of magnetization (M1) in a desired direction. A bit of data stored in the data layer (11) is read by measuring a potential difference between the data layer (11) and the soft reference layer (17). The cladding (21) substantially reduces fringe magnetic fields that can corrupt the data stored in neighboring tunnel junctions, the soft reference layer (17) reduces the number of layers needed to form a reference layer having a pinned orientation of magnetization, and a magnitude of the read current sufficient to read the bit of data is reduced by the soft reference layer (17).
