Positive spin polarization in Co/AlO3 /Co tunnel junctions driven by oxygen adsorption

Positive spin polarization in Co/AlO 3 /Co tunnel junctions driven by oxygen adsorption" (2005). Using a first-principles Green's function technique, we study spin-dependent tunneling in two model real-izations of ͑111͒ fcc Co/ Al 2 O 3 / Co tunnel junctions assuming O-terminated crystalline epitaxy in the corun-dum structure. For the first model, which includes 3 O atoms at the interface, the tu...

Positive spin polarization in Co/Al2O3/Co tunnel junctions driven by oxygen adsorption

Using a first-principles Green’s function technique, we study spin-dependent tunneling in two model realizations of 111 fcc Co/Al2O3/Co tunnel junctions assuming O-terminated crystalline epitaxy in the corundum structure. For the first model, which includes 3 O atoms at the interface, the tunneling current is polarized negatively, just as for the clean Co surface. The second model contains addi...

Origin of interfacial perpendicular magnetic anisotropy in MgO/CoFe/metallic capping layer structures

Spin-transfer-torque magnetic random access memory (STT-MRAM) attracts extensive attentions due to its non-volatility, high density and low power consumption. The core device in STT-MRAM is CoFeB/MgO-based magnetic tunnel junction (MTJ), which possesses a high tunnel magnetoresistance ratio as well as a large value of perpendicular magnetic anisotropy (PMA). It has been experimentally proven th...
