Abstract
A magnetoresistive (MR) sensor having electrically conductive lead structures which are in electrical contact with the MR element at spaced positions. The lead structures comprise a thin film layer of body-centered-cubic tantalum which is separated from the MR element by a thin film seed layer formed of a material taken from the group consisting of TiW, TaW, Cr and W.
