We compare magnetoresistances (MR) and switching currents (I_s) at room
temperature (295K) and 4.2K for Permalloy/N/Permalloy nanopillars undergoing
current-induced magnetization switching (CIMS), with non-magnetic metals N =
Cu, Ag, and Au. The N-metal thickness is held fixed at 10 nm. Any systematic
differences in MR and I_s for the different N-metals are modest, suggesting
that Ag and Au represent potentially viable alternatives for CIMS studies and
devices to the more widely used Cu.Comment: Submitted for Magnetism Conference, MMM-0
