Abstract: It is important for a CPP GMR read head that it have both high resistance as well as high cross-sectional area. This has been achieved by inserting a NOL (nano-oxide layer) though the middle of one or both of the two non-magnetic conductive layers. A key feature is that the NOL is formed by first depositing the conductive layer to about half its normal thickness. Then a metallic film is deposited thereon to a thickness that is low enough for it to still consist of individual islands. The latter are then fully oxidized without significantly oxidizing the conductive layer on which they lie. The remainder of the conductive layer is then deposited to a thickness sufficient to fully enclose the islands of oxide.

Abstract: A spin valve structure and a method for manufacturing it are described. The spin valve uses a modified pinned layer that consists of two cobalt iron layers separated by a layer of either ruthenium, iridium, or rhodium. A key feature of the invention is that this spacer layer is significantly thinner (typically 3-4 Angstroms) than similar layers in prior art structures. Normally, when such thin spacer layers are used, annealing fields in excess of 20,000 Oersted are needed to cause the two cobalt iron layers to become antiparallel. The present invention, however, teaches that much lower annealing fields (spanning a limited range) may be used with equal effect. The result is that a very high internal pinning field is created giving devices of this type greater pinned layer stability and reduced pinning reversal. These devices also exhibits a minimum amount of open looping in their hysteresis curves.
