Spontaneous and externally driven quantum spin fluctuations of 3d and 4d single atoms adsorbed on graphene
Siham Sadki, Filipe Souza Mendes Guimarães, Juba Bouaziz +3
At the heart of current information nanotechnology lies the search for ideal platforms hosting the smallest possible magnets, i.e. single atoms with magnetic moments pointing out-o…
Equivalence of wave function matching and Green's functions methods for quantum transport: generalized Fisher-Lee relation
Hocine Boumrar, Mahdi Hamidi, Hand Zenia +1
We present a proof of an exact equivalence of the two approaches that are most used in computing conductance in quantum electron and phonon transport: the wave function matching an…
Spin, atomic and inter-atomic orbital magnetism induced by 3d nanostructures deposited on transition metal surfaces
Sascha Brinker, Manuel dos Santos Dias, Samir Lounis
We present a first-principles study of the surface magnetism induced by Cr, Mn, Fe and Co adatoms on the (111) surfaces of Rh, Pd, Ag, Ir, Pt and Au. We first describe how the diff…
DFT+U Investigation of magnetocrystalline anisotropy of Mn-doped transition-metal dichalcogenides monolayers
Adlen Smiri, Sihem Jaziri, Samir Lounis +1
Doped transition-metal dichalcogenides monolayers exhibit exciting magnetic properties for the benefit of two-dimensional spintronic devices. Using density functional theory (DFT)…
Defect-implantation for the all-electrical detection of non-collinear spin-textures
Imara Lima Fernandes, Mohammed Bouhassoune, Samir Lounis
The viability of past, current and future devices for information technology hinges on their sensitivity to the presence of impurities. The latter can lead to resistivity anomalies…
Spin-orbit torques and their associated effective fields from gigahertz to terahertz
Filipe S. M. Guimarães, Juba Bouaziz, Manuel dos Santos Dias +1
Terahertz spintronics offers the prospect of devices which are both faster and more energy-efficient. A promising route to achieve this goal is to exploit current-induced spin-orbi…
