Lithography-free study of spin torque
نویسنده
چکیده
We developed a non-lithographic technique to contact sub-100nm nanowires for spin transfer torque experiments. Co/Cu multilayers were grown by electrodeposition in nanoporous commercial polycarbonate membranes from a Co/Cu bath. A home-made sample holder allows bottom and top electrical contacts to be made to individual nanowires in the CPP geometry. Experimental evidence of the spin transfer torque effect is given for (Co/Cu)n multilayers by recording dV/dI spectra as a function of the DC current amplitude. & 2009 Elsevier B.V.

Efficient High-Frequency Spin-Torque Oscillators Composed of Two Three-Layer MgO-MTJs with a Common Free Layer
We present a novel spin-torque oscillator based on two three-layer MgO-MTJs with a shared free layer. By performing extensive micromagnetic simulations we found that the structure exhibits a wide tunability of oscillation frequencies from a few GHz to several tens of GHz. We discuss the optimization of such structures in order to obtain the maximum output power. Keywords—spin-torque; oscillator...
متن کاملSpin torque, tunnel-current spin polarization, and magnetoresistance in MgO magnetic tunnel junctions.
We employ the spin-torque response of magnetic tunnel junctions with ultrathin MgO tunnel barrier layers to investigate the relationship between spin transfer and tunnel magnetoresistance (TMR) under finite bias, and find that the spin torque per unit current exerted on the free layer decreases by < 10% over a bias range where the TMR decreases by > 40%. This is inconsistent with free-electron-...
متن کاملTime-resolved spin-torque switching and enhanced damping in permalloy/Cu/permalloy spin-valve nanopillars.
We report time-resolved measurements of current-induced reversal of a free magnetic layer in Permalloy/Cu/Permalloy elliptical nanopillars at temperatures T=4.2 K to 160 K. Comparison of the data to Landau-Lifshitz-Gilbert macrospin simulations of the free layer switching yields numerical values for the spin torque and the Gilbert damping parameters as functions of T. The damping is strongly T ...

New types of spintronics devices utilizing all-electrical magnetization manipulation by current, such as spin-torque transfer RAM and spin-torque oscillators, have been developed based on MgO magnetic tunnel junctions (MTJs) with a large magneto-resistance ratio [1]. Spin-torque oscillators based on a single MTJ with in-plane magnetization [2] show high frequency capabilities, but still need an...
