Quantum Spin Transfer of Spin-Correlated Electron Pairs
Seongmun Hwang, Jung Hyun Oh, Paul M. Haney +2
We theoretically investigate quantum spin transfer from spin-correlated conduction-electron pairs to localized spins in a ferromagnet, given that electrons are correlated intrinsic…
Nonlocal Transport in Cr-doped (Bi,Sb)2Te3: Absence of Nonchiral Edge States
Valery Ortiz Jimenez, Paul M. Haney, Farzad Mahfouzi +3
The quantum anomalous Hall effect shows great promise for realization of the ohm without the need for an external magnetic field. The most mature material platform is magnetically…
Electric Field-Induced Kerr Rotation on Metallic Surfaces
Farzad Mahfouzi, Mark D. Stiles, Paul M. Haney
We use a combination of density functional theory calculations and optical modeling to establish that the electric field-induced Kerr rotation in metallic thin films has contributi…
Metallic Electro-Optic Effect in Twisted Double-Bilayer Graphene
D. J. P. de Sousa, N. Roldan-Levchenko, C. O. Ascencio +3
Recent theoretical advances have highlighted the role of Bloch state intrinsic properties in enabling unconventional electro-optic (EO) phenomena in bulk metals, offering novel str…
Current-Induced Circular Dichroism on Metallic Surfaces: A First-Principles Study
Farzad Mahfouzi, Mark D. Stiles, Paul M. Haney
We use {\it ab initio} calculations to understand the current-induced optical response and orbital moment accumulation at the surfaces of metallic films. These two quantities are r…
Breakdown of the drift-diffusion model for transverse spin transport in a disordered Pt film
K. D. Belashchenko, G. G. Baez Flores, W. Fang +4
Spin accumulation and spin current profiles are calculated for a disordered Pt film subjected to an in-plane electric current within the nonequilibrium Green function approach. In…
Gigantic tunneling magnetoresistance in magnetic Weyl semimetal tunnel junctions
D. J. P. de Sousa, C. O. Ascencio, P. M. Haney +2
We investigate the tunneling magnetoresistance in magnetic tunnel junctions (MTJs) comprised of Weyl semimetal contacts. We show that chirality-magnetization locking leads to a gig…
Intrinsic spin currents in ferromagnets
V. P. Amin, Junwen Li, M. D. Stiles +1
First principles calculations show that electric fields applied to ferromagnets generate spin currents flowing perpendicularly to the electric field. Reduced symmetry in these ferr…
