Abstract
A magnetoresistive head includes an underlayer composed of one of Ni and NiFe alloy and at least one additive selected from the group consisting of Cr, Nb, Rh, and Pd. An anti-ferromagnetic layer is formed on the underlayer, and a first ferromagnetic layer is formed on the anti-ferromagnetic layer. The magnetic head also includes a nonmagnetic layer formed on the first ferromagnetic layer, and a second ferromagnetic layer formed on the nonmagnetic layer.
