Lithography-free study of spin torque

We developed a non-lithographic technique to contact sub-100 nm nanowires for spin transfer torque experiments. Co/Cu multilayers were grown by electrodeposition in nanoporous commercial polycarbonate membranes from a Co/Cu bath. A home-made sample holder allows bottom and top electrical contacts to be made to individual nanowires in the CPP geometry. Experimental evidence of the spin transfer torque effect is given for (Co/Cu)n multilayers by recording dV/dI spectra as a function of the DC current amplitude.
