Spin transfer torques generated by the anomalous Hall effect and anisotropic magnetoresistance
Tomohiro Taniguchi, J. Grollier, M. D. Stiles
Spin-orbit coupling in ferromagnets gives rise to the anomalous Hall effect and the anisotropic magnetoresistance, both of which can be used to create spin-transfer torques in a si…
Laser doping for ohmic contacts in n-type Ge
F. Chiodi, A. D. Chepelianskii, C. Gardes +3
We achieved ohmic contacts down to 5 K on standard n-doped Ge samples by creating a strongly doped thin Ge layer between the metallic contacts and the Ge substrate. Thanks to the l…
Spintronics with graphene
Pierre Seneor, Bruno Dlubak, Marie-Blandine Martin +3
Because of its fascinating electronic properties, graphene is expected to produce breakthroughs in many areas of nanoelectronics. For spintronics, its key advantage is the expected…
Graphene-Passivated Nickel as an Oxidation-Resistant Electrode for Spintronics
Bruno Dlubak, Marie-Blandine Martin, Robert S. Weatherup +9
We report on graphene-passivated ferromagnetic electrodes (GPFE) for spin devices. GPFE are shown to act as spin-polarized oxidation-resistant electrodes. The direct coating of nic…
Evidence for anisotropic dielectric properties of monoclinic hafnia using high-resolution TEM valence electron energy-loss spectroscopy and ab initio time-dependent density-functional theory
Cyril Guedj, Linda Hung, Alberto Zobelli +3
The effect of nanocrystal orientation on the energy loss spectra of monoclinic hafnia (m-HfO) is measured by high resolution transmission electron microscopy (HRTEM) and valenc…
Resistive switching phenomena in TiOx nanoparticle layers for memory applications
Emanuelle Goren, Mariana Ungureanu, Raul Zazpe +5
Electrical characteristics of a Co/TiO_x/Co resistive memory device, fabricated by two different methods are reported. In addition to crystalline TiO_2 layers fabricated via conven…
