Abstract
A soft adjacent layer made from a ternary alloy material and a MR sensor utilizing this soft adjacent layer. The ternary alloy material CoXY includes cobalt (Co), a first transition metal X and a second transition metal Y. In a preferred embodiment, X is niobium (Nb) and Y is titanium (Ti) so that the resulting ternary alloy material is CoNbTi. Alternatively, X and Y may be any transition metals such that the resulting ternary alloy material CoXY exhibits properties similar to CoNbTi. The high-density MR sensor of the present invention includes a SAL made from the ternary alloy material, a MR layer and a non-magnetic spacer sandwiched between the SAL and MR layer.
