Studies of Effects of Current on Exchange-Bias: A Brief Review
J. Bass, A. Sharma, Z. Wei +1
MacDonald and co-workers recently predicted that high current densities could affect the magnetic order of antiferromagnetic (AFM) multilayers, in ways similar to those that occur…
Point-contact search for antiferromagnetic giant magnetoresistance
Z. Wei, A. Sharma, J. Bass +1
We report the first measurements of effects of large current densities on current-perpendicular-to-plane magnetoresistance (MR) of magnetic multilayers containing two antiferromagn…
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/…
