Sensitivity of Ag/Al Interface Specific Resistances to Interfacial Intermixing
A. Sharma, N. Theodoropoulou, Shuai Wang +3
We have measured an Ag/Al interface specific resistance, 2AR(Ag/Al)(111) = 1.4 fOhm-m^2, that is twice that predicted for a perfect interface, 50% larger than for a 2 ML 50%-50% al…
Spin-Diffusion Lengths in Dilute Cu(Ge) and Ag(Sn) Alloys
Q. Fowler, B. Richard, A. Sharma +4
We use current-perpendicular-to-plane (CPP) exchange-biased spin-valves to directly measure spin diffusion lengths lsf for N = Cu(2.1 at.%Ge) and Ag(3.6 at.%Sn) alloys. We find lsf…
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…
Ballistic vs Diffusive Transport in Current-Induced Magnetization Switching
N. Theodoropoulou, A. Sharma, W. P. Pratt +3
We test whether current-induced magnetization switching due to spin-transfer-torque in ferromagnetic/non-magnetic/ferromagnetic (F/N/F) trilayers changes significantly when scatter…
Spin transfer in an antiferromagnet
Z. Wei, A. Sharma, A. S. Nunez +5
An electrical current can transfer spin angular momentum to a ferromagnet. This novel physical phenomenon, called spin transfer, offers unprecedented spatial and temporal control o…
