ترابرد الکتریکی وابسته به اسپین در ساختارهای نامتجانس Fe-MgO-Fe
In this paper, spin-dependent electrical transport properties are investigated in a single-crystal magnetic tunnel junction (MTJ) which consists of two ferromagnetic Fe electrodes separated by an MgO insulating barrier. These properties contain electric current, spin polarization and tunnel magnetoresistance (TMR). For this purpose, spin-dependent Hamiltonian is described for Δ1 and Δ5 bands in...
متن کاملBallistic electron magnetic microscopy: Imaging magnetic domains with nanometer resolution
A variation of ballistic electron emission microscopy has been developed to image magnetic structure in thin-film multilayers with nanometer resolution. In studies of nominally uncoupled Co/Cu/Co trilayer films, magnetic domains and domain-wall motion are readily observable with this technique. In the Co/Cu/Co trilayer system magnetic domains are found to occur on an ;500-nm-length scale and le...
متن کاملCoherent Control of Nanoscale Ballistic Currents in Transition Metal Dichalcogenide ReS2.
Transition metal dichalcogenides are predicted to outperform traditional semiconductors in ballistic devices with nanoscale channel lengths. So far, experimental studies on charge transport in transition metal dichalcogenides are limited to the diffusive regime. Here we show, using ReS2 as an example, all-optical injection, detection, and coherent control of ballistic currents. By utilizing qua...
متن کاملSpin-polarized transport through a zigzag-edge graphene flake embedded between two armchair nanoribbons electrodes
We study the coherent spin-polarized transport through a zigzag-edge graphene flake (ZGF), using Hubbard model in the nearest neighbor approximation within the framework of the Green function’s technique and Landauer formalism. The system considered consists of electrode/ (ZGF)/electrode, in which the electrodes are chosen to be armchair nanoribbons. The study was performed for two types of ele...
متن کاملSpin-wave localization in disordered magnets
The propagation of spin waves [1] is in the focus of modern research because of its importance for spin caloritronic applications [2–6], and for future information processing devices which might either rely on magnonic [7] instead of electronic transport or combine electronic with magnonic transport. The dynamics of spin waves is mostly described by the Landau-Lifshitz-Gilbert equation, a nonli...
