Proximity magnetoresistance in graphene induced by magnetic insulators
D. A. Solis, A. Hallal, X. Waintal +1
We demonstrate the existence of Giant proximity magnetoresistance (PMR) effect in a graphene spin valve where spin polarization is induced by a nearby magnetic insulator. PMR calcu…
Intrinsic spin orbit torque in a single domain nanomagnet
A. Kalitsov, S. A. Nikolaev, J. Velev +2
We present theoretical studies of the intrinsic spin orbit torque (SOT) in a single domain ferromagnetic layer with Rashba spin-orbit coupling (SOC) using the non-equilibrium Green…
Direct evidence for minority spin gap in the Co2MnSi Heusler alloy
Stéphane Andrieu, Amina Neggache, Thomas Hauet +6
Half Metal Magnets are of great interest in the field of spintronics because of their potential full spin-polarization at the Fermi level and low magnetization damping. The high Cu…
Impurity induced enhancement of perpendicular magnetic anisotropy in Fe/MgO tunnel junctions
A. Hallal, B. Dieny, M. Chshiev
Using first-principles calculations, we investigated the impact of chromium (Cr) and vanadium (V) impurities on the magnetic anisotropy and spin polarization in Fe/MgO magnetic tun…
Anatomy of perpendicular magnetic anisotropy in Fe/MgO magnetic tunnel junctions: First principles insight
A. Hallal, H. X. Yang, B. Dieny +1
Using first-principles calculations, we elucidate microscopic mechanisms of perpendicular magnetic anisotropy (PMA)in Fe/MgO magnetic tunnel junctions through evaluation of orbital…
Analytical description of ballistic spin currents and torques in magnetic tunnel junctions
M. Chshiev, A. Manchon, A. Kalitsov +5
In this work we demonstrate explicit analytical expressions for both charge and spin currents which constitute the 2x2 spinor in magnetic tunnel junctions with noncollinear magneti…
Diffusive model of current-in-plane-tunneling in double magnetic tunnel junctions
Pierre-Yves Clément, Clarisse Ducruet, Claire Baraduc +2
We propose a model that describes current-in-plane tunneling transport in double barrier magnetic tunnel junctions in diffusive regime. Our study shows that specific features appea…

A. Vedyayev, N. Strelkov, M. Chshiev +2
Spin accumulation and spin transfer torques induced by Spin Hall Effect in bi-layer structures comprising ferromagnetic and paramagnetic materials are theoretically investigated. T…
Spin-current vortices in current-perpendicular-to-plane nanoconstricted spin-valves
N. Strelkov, A. Vedyayev, N. Ryzhanova +7
The charge and spin diffusion equations taking into account spin-flip and spin-transfer torque were numerically solved using a finite element method in complex non-collinear geomet…
The two-bands model of the magnetic tunnel junctions in the Fe/Cr/MgO/Fe structure

In this paper we present theoretical studies of spin dependent transport in Fe/Cr/MgO/Fe tunnel junctions with non-collinear alignment of magnetizations of metallic layers comprisi…
Half-Metallic L2 Structures with (001) Planar Insertions
C. A. Culbert, M. Williams, M. Chshiev +1
A number of L2 phase alloys (composition XYZ) are half-metallic. Although this structure is typically described in terms of an fcc Bravais lattice with a 4 atom basis, it c…
