Temperature-Dependent Spin-Orbit Torque Generation in Perpendicularly Magnetized Topological Insulator-Magnetic Multilayer Heterostructures
Soumyarup Hait, Benjamin A. Brereton, Ahmet Yagmur +3
We report a comprehensive temperature-dependent investigation of spin-orbit torque (SOT) generation in heterostructures comprising a perpendicularly magnetized metallic multilayer…
Second harmonic generation and third harmonic generation in topological insulator-based van der Waals metamaterials
Alessandra Di Gaspare, Sara Ghayeb, Craig Knox +3
High-order harmonic generation (HHG) in solids - the frequency up-conversion of an optical signal - is governed by symmetries. At terahertz (THz) frequencies, HHG is a key technolo…
Tailoring Ultrathin Magnetic Multilayers at Terraced Topologically Insulating Interfaces for Perpendicularly Magnetized Domains
Benjamin A. Brereton, Soumyarup Hait, Ahmet Yagmur +8
Topological insulators and skyrmion-hosting, chiral magnetic multilayers are two well-explored areas of modern condensed matter physics, each offering unique advantages for spintro…
Tuning the Electronic States of Bi2Se3 Films with Large Spin-Orbit Interaction Using Molecular Heterojunctions
Matthew Rogers, Craig Knox, Bryan Hickey +13
An electric bias can shift the Fermi level along the Dirac cone of a topological insulator and modify its charge transport, but tuning the electronic states and spin-orbit interact…
