A magnetic head including an electrical lead layer that is comprised of a
material having an ordered crystalline structure. In a preferred
embodiment, the ordered crystalline structure of the electrical lead is
epitaxially matched to the crystalline structure of the hard bias layer
upon which it is formed, and there is no need for a seed layer for the
electrical leads. Electrical leads having an ordered crystalline
structure, particularly a B2, L1.sub.0, L1.sub.1, L1.sub.2 and D0.sub.3
structure, will have significantly reduced resistivity over the prior art
electrical leads that are typically composed of rhodium or tantalum. As a
result, thinner electrical leads can be fabricated which carry the same,
or even greater, current than the prior art rhodium or tantalum leads.
The preferred leads are comprised of NiAl having a B2 crystalline
structure, and alternative embodiments are comprised of CuAu, Cu.sub.3Au,
Ni.sub.3Al and Fe.sub.3Al.
