Current-induced spin polarization in chiral Tellurium: a first-principles quantum transport study
Reena Gupta, Andrea Droghetti
Te is a naturally p-doped semiconductor with a chiral structure, where an electrical current causes the conduction electrons to become spin polarized parallel to the transport dire…
Current-induced spin polarization at metallic surfaces from first-principles
Andrea Droghetti, Ilya V. Tokatly
We present the results of first-principles calculations based on density functional theory estimating the magnitude of the current-induced spin polarization (CISP) at the surfaces…
A theoretical perspective on the modification of the magnetocrystalline anisotropy at molecule-cobalt interfaces
Anita Halder, Sumanta Bhandary, David D. O'Regan +2
We study the modification of the magnetocrystalline anisotropy (MCA) of Co slabs induced by several different conjugated molecular overlayers, i.e., benzene, cyclooctatetraene, nap…
Dynamical Mean-Field Theory for spin-dependent electron transport in spin-valve devices
Andrea Droghetti, Milos M. Radonjić, Liviu Chioncel +1
We present the combination of Density Functional Theory (DFT) and Dynamical Mean Field Theory (DMFT) for computing the electron transmission through two-terminals nanoscale devices…
Spin-orbit induced equilibrium spin currents in materials
Andrea Droghetti, Ivan Rungger, Angel Rubio +1
The existence of spin-currents in absence of any driving external fields is commonly considered an exotic phenomenon appearing only in quantum materials, such as topological insula…
Oxygen doping and polaron magnetic coupling in Alq films
Andrea Droghetti
The understanding of the Physics underlying the performances of organic spin-valve devices is still incomplete. According to some recent models, spin transport takes place in an im…
