Spin Transfer Switching and Spin Polarization in Magnetic Tunnel Junctions with Mgo and Alox Barriers
Zhitao Diao, Dmytro Apalkov, Mahendra Pakala +2
We present spin transfer switching results for MgO based magnetic tunneling junctions (MTJs)with large tunneling magnetoresistance (TMR) ratio of up to 150% and low intrinsic switc…
Spin-Polarized Current Induced Torque in Magnetic Tunnel Junctions
A. Kalitsov, I. Theodonis, N. Kioussis +3
We present tight-binding calculations of the spin torque in non-collinear magnetic tunnel junctions based on the non-equilibrium Green functions approach. We have calculated the sp…
Observation of spin-transfer switching in deep submicron-sized and low-resistance magnetic tunnel junctions
Yiming Huai, Frank Albert, Paul Nguyen +2
The spin-transfer effect has been studied in magnetic tunnel junctions (PtMn/CoFe/Ru/CoFe/Al2O3/CoFe/NiFe) with dimensions down to 0.1x0.2 um2 and resistance-area product RA in the…
Critical Current Distribution in Spin Transfer Switched Magnetic Tunnel Junctions
Mahendra Pakala, Yiming Huai, Thierry Valet +2
The spin transfer switching current distribution within a cell was studied in magnetic tunnel junction based structures having alumina barriers with resistance-area product (RA) of…
