Ultrathin perpendicular free layers for lowering the switching current in STT-MRAM
Tiffany S. Santos, Goran Mihajlovic, Neil Smith +4
The critical current density required for switching the magnetization of the free layer (FL) in a spin-transfer torque magnetic random access memory (STT-MRAM) cell is pro…
Thermal stability for domain wall mediated magnetization reversal in perpendicular STT MRAM cells with W insertion layers
G. Mihajlovic, N. Smith, T. Santos +3
We present an analytical model for calculating energy barrier for the magnetic field-driven domain wall-mediated magnetization reversal of a magneto-resistive random access memory…
Origin of the resistance-area product dependence of spin transfer torque switching in perpendicular magnetic random access memory cells
Goran Mihajlovic, Neil Smith, Tiffany Santos +5
We report on an experimental study of current induced switching in perpendicular magnetic random access memory (MRAM) cells with variable resistance-area products (RAs). Our result…
Modulation of Spin Accumulation by Nanoscale Confinement using Electromigration in a Metallic Lateral Spin Valve
Emmanouil Masourakis, Libe Arzubiaga, Goran Mihajlović +4
We study spin transport in lateral spin valves with constricted channels. Using electromigration, we modulate the spin accumulation by continuously varying the width of the non-mag…
Evidence of Vortex Jamming in Abrikosov Vortex Flux Flow Regime
G. Karapetrov, V. Yefremenko, G. Mihajlović +4
We report on dynamics of non-local Abrikosov vortex flow in mesoscopic superconducting Nb channels. Magnetic field dependence of the non-local voltage induced by the flux flow show…
Temperature dependent nucleation and annihilation of individual magnetic vortices
G. Mihajlovic, M. S. Patrick, J. E. Pearson +5
We studied the temperature dependence of the magnetization reversal in individual submicron permalloy disks with micro-Hall and bend-resistance magnetometry. The nucleation field e…
Surface spin flip probability of mesoscopic Ag wires
G. Mihajlovic, J. E. Pearson, S. D. Bader +1
Spin relaxation in mesoscopic Ag wires in the diffusive transport regime is studied via nonlocal spin valve and Hanle effect measurements performed on permalloy/Ag lateral spin val…
Imaging of lateral spin valves with soft X-ray microscopy
O. Mosendz, G. Mihailovic, J. E. Pearson +4
We investigated Co/Cu lateral spin valves by means of high-resolution transmission soft x-ray microscopy with magnetic contrast that utilizes x-ray magnetic circular dichroism (XMC…
Negative nonlocal resistance in mesoscopic gold Hall bars: Absence of giant spin Hall effect
G. Mihajlovic, J. E. Pearson, M. A. Garcia +2
We report the observation of negative nonlocal resistances in multiterminal mesoscopic gold Hall bar structures whose characteristic dimensions are larger than the electron mean-fr…
