Enhanced spin-to-charge conversion in LaSrMnO/NdNiO bilayers at the nickelate metal-insulator phase transition
Biswajit Sahoo, Sarmistha Das, Akilan K +6
Phase transition materials such as NdNiO3 (NNO) when coupled with low damping ferromagnets such as LaSrMnO (LSMO) can lead to new multi-functional material sy…
Spin transport properties of spinel vanadate-based heterostructures
Antonio Peña Corredor, Alberto Anadón, Laurent Schlur +7
Spin-orbit coupling and breaking of inversion symmetry are necessary ingredients to enable a pure spin current-based manipulation of the magnetization via the spin-orbit torque eff…

Iridium is a very promising material for spintronic applications due to its interesting magnetic properties such as large RKKY exchange coupling as well as its large spin-orbit cou…
Spin dependent transport characterization in metallic lateral spin valves using 1D and 3D modeling
P. Laczkowski, M. Cosset-Cheneau, W. Savero-Torres +8
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 analy…
Evidence of Pure Spin-Current Generated by Spin Pumping in Interface Localized States in Hybrid Metal-Silicon-Metal Vertical Structures
C. Cerqueira, J. Y. Qin, H. Dang +20
Due to the difficulty to grow high quality semiconductors on ferromagnetic metals, the study of spin diffusion transport in Si was only limited to lateral geometry devices. In this…
Charge-spin current conversion in high quality epitaxial Fe/Pt systems: isotropic spin Hall angle along different in-plane crystalline directions
