The in-plane current profile within multilayers of the generic structure Ta/Pt/(CoNi)/Pt/Ta is investigated. A large set of samples where the thickness of each layer was systematically varied was grown, followed by the measurement of the sheet resistance of each sample. The data are analyzed by a series of increasingly elaborate models, from a macroscopic engineering approach to mesoscopic transport theory. Non-negligible variations of the estimated repartition of current between the layers are…

Unconventional anomalous Hall effect in 3d/5d multilayers mediated by the nonlocal spin-conductivity.

We evidenced unconventionnal Anomalous Hall Effects (AHE) in 3d/5d (Co0.2nm/Ni0.6nm)N multilayers grown on a thin Pt layer or thin Au:W alloy. The inversion observed on AHE originates from the

Fully resolved currents from quantum transport calculations

We extract local current distributions from interatomic currents calculated using a fully relativistic quantum mechanical scattering formalism by interpolation onto a three-dimensional grid. The

Anomalous Hall effect in 3d/5d multilayers mediated by interface scattering and nonlocal spin conductivity

We have evidenced unconventional anomalous Hall effects (AHEs) in $3d/5d$ (${\mathrm{Co}0.2\mathrm{nm}/\mathrm{Ni}0.6\mathrm{nm})}_{N}$ multilayers grown on a thin Pt layer or thin Au:W alloys with

Thermal Annealing Effect on GaSb Thin Films Deposited on Si (001) for Assembly of GaSb/Mn Multilayer Systems at Room Temperature

Sub-band resistivities of concentrated nickel alloys and spontaneous resistivity anisotropy

The transport properties of disordered concentrated ferromagnetic NiT alloys, with T=Cr, Fe, Co or Cu, are analysed at low temperatures within the framework of the two-current model. A theoretical

Electrical Conductivity of Thin Metallic Films with Unlike Surfaces

A theoretical analysis, based on the Fuchs‐Sondheimer formalism, is given of the conductivity of single‐layer, thin metallic films in which the scattering of the conduction electrons is different at


A model is developed for estimating effects due to electron scattering from grain boundaries, occurring simultaneously with background scattering. Since grain‐boundary effects are negligible in bulk

Switching the magnetic configuration of a spin valve by current-induced domain wall motion

We present experimental results on the displacement of a domain wall by injection of a dc current through the wall. The samples are 1-μm-wide long stripes of a CoO/Co/Cu/NiFe classical spin-valve

A new theory of the size effect in electrical conduction

Conventionally, the theory of boundary scattering ignores the dependence of the reflection coefficient (p) on the electron wave vector. An alternative possibility, that the reflection coefficient

Electrical-Resistivity Model for Polycrystalline Films: the Case of Arbitrary Reflection at External Surfaces

In this paper, the total resistivity of a thin metal film is calculated from a model in which three types of electron scattering mechanisms are simultaneously operative: an isotropic background

Resistivity and Temperature Coefficient of Thin Metal Films with Rough Surface

The thickness dependence of resistivity and its temperature coefficient of thin metal films has been studied. A theory is proposed to include, the surface roughness in determining the film

Preparation and properties of thin amorphous tantalum films formed by small e-beam evaporators

Large area (A = 6 cm2), thin tantalum films (5 nm < d < 100 nm) are accomplished by evaporation from tantalum rods using small pocket e-beam evaporators. Using a sample to source distance of ≈20 cm,
