We propose a nonlocal spin-valve measurement combined with a local spin-valve structure to enlarge spin signal. The probe configuration consists of a lateral spin valve with three Ni–Fe wires bridged by a Cu wire. The advantage is that the spin polarization in the Cu wire induced by the spin injection can be enhanced compared to the conventional method.

    As a differential dual spin valve (DDSV) consists of two SVs separated by a gap layer, in addition to the interlayer couplings between the free layer (FL) and its reference layer in each SV, it is important to understand the interaction between the two FLs and its effect on reading performances....

    Sputter-deposited, equiatomic PtMn thin films have application in giant magnetoresistive spin valves, tunneling magnetoresistive spin valves, and magnetic random access memory. However, the as-deposited films are found to be a disordered A1 phase in a paramagnetic state rather than an...
