Abstract
An approach for calculating spin transfer torque including interfacial scattering effects in structures consisting of multiple ferromagnet/nonmagnet (FM/NM) bilayers was developed. Using this approach, a micromagnetic analysis on structures consisting of six magnetic layers was compared to electrical measurements on electrodeposited Co/Cu multilayered nanowires. Good agreement with experiment was achieved if it was assumed that one of the layers is magnetically fixed. An array of 16 wires, each consisting of 6 FM/NM bilayers, was also micromagnetically modeled and compared to a similar experimental measurement. Both results confirm that including a wide distribution of wires results in a less uniform switching mechanism.
