摘要
A current perpendicular-to-the-plane magnetoresistance (CPP-MR) device includes a first magnetic shield, a second magnetic shield, and a spin valve structure. The first and second magnetic shields are formed of an electrically conductive and magnetically shielding material. A read gap is defined between the first and second magnetic shields, and the spin valve structure is disposed between the first and second magnetic shields. The spin valve structure is electrically connected and magnetically separated from the first and second magnetic shields such that the first and second magnetic shields act as electrical contact leads.
