Studies of dc Current-Driven Switching in Py/N/Py magnetic nanopillars
S. Urazhdin, W. P. Pratt, J. Bass
We provide new data on current-driven switching in Permalloy (Py = Ni84Fe16) based nanopillars at room temperature and 4.2K that confirm and extend previously published work. We pr…

Studies of Current-Driven Excitations in Co/Cu/Co Trilayer Nanopillars
S. Urazhdin, Norman O. Birge, W. P. Pratt +1
We measure the dynamic resistance of a Co/Cu/Co trilayer nanopillar at varied magnetic field and current . The resistance displays the usual behavior, almost symmetric in $H…

Effect of Interlayer Coupling on Current-Assisted Magnetization Switching in Nanopillars
S. Urazhdin, W. P. Pratt, J. Bass
We show that dipole-field induced antiferromagnetic coupling, or RKKY ferromagnetic coupling, between Co layers can strongly affect the low magnetic field switching behavior of Co/…
