چکیده
The electronic ground-state properties of Fe/semiconductor/Fe~001! tunnel junctions are studied by means of the ab initio screened Korringa-Kohn-Rostoker method. We focus on the magnetic properties, charge transfer, local, and qi-resolved density of states of these systems. We consider in detail Fe/ZnSe/Fe~001! tunnel junctions and compare their electronic properties with junctions with Si and GaAs barriers. We discuss the results in connection to the spin-dependent transport properties expected for these systems.

Ballistic spin injection and detection in FeÕsemiconductorÕFe junctions
We present ab initio calculations of the spin-dependent electronic transport in Fe/GaAs/Fe and Fe/ZnSe/Fe ~001! junctions simulating the situation of a spin-injection experiment. We follow a ballistic Landauer-Büttiker approach for the calculation of the spin-dependent dc conductance in the linear-response regime, in the limit of zero temperature. We show that the bulk band structure of the lea...

We present tunneling experiments on Fe~001!/MgO~20 Å!/FeCo~001! single-crystal epitaxial junctions of high quality grown by sputtering and laser ablation. Tunnel magnetoresistance measurements give 60% at 30 K, to be compared with 13% obtained recently on ~001!-oriented Fe/amorphous-Al2O3 /FeCo tunnel junctions. This difference demonstrates that the spin polarization of tunneling electrons is n...
متن کاملAtomic and electronic structure of CoÕSrTiO3 ÕCo magnetic tunnel junctions
First-principles density-functional calculations of the atomic and electronic structure of Co/SrTiO3 /Co ~001! magnetic tunnel junctions ~MTJ’s! are performed. Different interface terminations are considered and the most stable structure with the TiO2 termination is identified based on energetics of adhesion. The calculated electronic structure of the TiO2-terminated MTJ shows an exchange coupl...
متن کاملEffects of structural relaxation on calculations of the interface and transport properties of Fe/MgO(001) tunnel junctions
The relaxation of the interface structure of Fe/MgO 100 magnetic tunnel junctions predicted by densityfunctional theory depends significantly on the choice of exchange and correlation functional. Bader analysis reveals that structures obtained by relaxing the cell with the local spin-density approximation LSDA display a different charge transfer than those relaxed with the generalized gradient ...
متن کاملOxygen-induced symmetrization and structural coherency in Fe/MgO/Fe(001) magnetic tunnel junctions.
We present x-ray diffraction experiments and multiple-scattering calculations on the structure and transport properties of a Fe/MgO/Fe(001) magnetic tunnel junction (MTJ). Coherent growth of the top Fe electrode on the MgO spacer is observed only for Fe deposition in ambient oxygen atmosphere leading to a coherent and symmetric MTJ structure characterized by FeO layers at both interfaces. This ...
