Spin-Polarized Electron Injection through an Fe/InAs Junction

Fully Polarized Spin Injection into Carbon Nanotubes

Appropriately doped perovskite oxides of manganese such as La2/3Sr1/3MnO3 (LSMO) are ferromagnetic metals in which the conduction electrons tend to be 100% spin polarised [5]. It is therefore desirable to fabricate CNT devices with LSMO electrodes. However, to integrate these two very different material systems into a single device is challenging since their growth conditions are potentially mu...

Spin-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...

Spin-polarized electron tunneling across magnetic dielectric

This letter deals with a magnetic tunnel junction having spin filtering by a magnetic barrier. We performed experiments in which a relatively strong external field rotates magnetizations of both ferromagnetic electrodes in the tunnel junction with the magnetic barrier simultaneously so that the two are always parallel to each other. The tunnel magnetoresistance induced in this way was over 16% ...
