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…
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…
Elasto-Dynamical Induced Spin and Charge Pumping in Bulk Heavy Metals
Farzad Mahfouzi, Nicholas Kioussis
Analogous to the Spin-Hall Effect (SHE), {\it ab initio} electronic structure calculations reveal that acoustic phonons can induce charge (spin) current flowing along (normal to) i…
Spin transfer torque in MnGa-based ferrimagnetic tunnel junctions from first principles
Maria Stamenova, Plamen Stamenov, Farzad Mahfouzi +3
We report on first-principles calculations of spin-transfer torque (STT) in epitaxial magnetic tunnel junctions (MTJs) based on ferrimagnetic tetragonal MnGa electrodes, both a…
Microscopic Origin of Spin-Orbit Torque in Ferromagnetic Heterostructures: A First Principles Approach
Farzad Mahfouzi, Rahul Mishra, Po-Hao Chang +2
We present an {\it ab initio}-based theoretical framework which elucidates the origin of the spin-orbit torque (SOT) in Normal-Metal(NM)/Ferromagnet(FM) heterostructures. The SOT i…
