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…
Strain effects on the fluctuation properties in noncollinear antiferromagnets: a first-principles and macrospin-based study
Mohammad M. Rahman, Farzad Mahfouzi, Matthew W. Daniels +1
We present a theoretical investigation of epitaxial strain effects on the magnetic fluctuation properties of MnSn noncollinear antiferromagnets. Employing density functional th…
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…
