Spin-dependent transport characterization in metallic lateral spin valves using one-dimensional and three-dimensional modeling Open
We present the analysis of the spin signals obtained in NiFe based metallic lateral spin valves. We exploit the spin dependent diffusive equations in both the conventional 1D analytic modeling as well as in 3D Finite Element Method simulat…

Spin diffusion length and polarization of ferromagnetic metals measured by the spin-absorption technique in lateral spin valves Open
We present measurements of pure spin current absorption on lateral spin\nvalves. By varying the width of the absorber we demonstrate that spin current\nabsorption measurements enable to characterize efficiently the spin transport\nproperti…

Large enhancement of the spin Hall effect in Au by side-jump scattering on Ta impurities Open
We present measurements of the Spin Hall Effect (SHE) in AuW and AuTa alloys\nfor a large range of W or Ta concentrations by combining experiments on lateral\nspin valves and Ferromagnetic-Resonance/spin pumping technique. The main result\…

Evaluation of the spin diffusion length of AuW alloy by spin absorption experiments in the limit of large spin-orbit interactions Open
The knowledge of the spin diffusion length $λ_{A}$ is a prerequisite for the estimation of the spin Hall angle. We investigate spin current absorption of materials with small $λ_{A}$ using AuW stripes inserted in lateral spin-valves. Width…

Large spin signals in metallic lateral spin-valves made with Co60Fe40 electrodes Open
Spin injection and detection in Co60Fe40-based all-metallic lateral spin-valves have been studied at both room and low temperatures. The obtained spin signals amplitudes have been compared to that of identical Ni80Fe20-based devices. The r…

Calculation method of spin accumulations and spin signals in nanostructures using spin resistors Open
The understanding and calculation of spin transport are essential elements for the development of spintronics devices. Here, we propose a simple method to calculate analytically the spin accumulations, spin currents and magnetoresistances …
