Two-Stage Proximity-Induced Gap-Opening in Topological Insulator - Insulating Ferromagnet (BiSb)Te - EuS Bilayers
Qi I. Yang, Aharon Kapitulnik
To further investigate the interplay between ferromagnetism and topological insulators, thin films of the low-carrier topological insulator (BiSb)Te were deposi…
Rigorous determination of the ground-state phases and thermodynamics in an Ising-type multiferroic Ca3CoMnO6 chain
Yan Qi, Qi Yang, Nai-sen Yu +1
To understand the collinear-magnetism-driven ferroelectricity in multiferroic Ca3CoMnO6 compound, we have established an elastic diatomic Ising spin-chain model with axial-next-nea…
Pulsed Laser Deposition of High-Quality Thin Films of the Insulating Ferromagnet EuS
Qi I. Yang, Jinfeng Zhao, Li Zhang +5
High-quality thin films of the ferromagnetic-insulator europium(II) sulfide (EuS) were fabricated by pulsed laser deposition on Al2O3 (0001) and Si (100) substrates. A single orien…
Weak Localization Effects as Evidence for Bulk Quantization in Thin Films Bi2Se3
Li Zhang, Merav Dolev, Qi I. Yang +5
Strong spin-orbit coupling in topological insulators results in the ubiquitously observed weak antilocalization feature in their magnetoresistance. Here we present magnetoresistanc…
Emerging Weak Localization Effects on Topological Insulator-Insulating Ferromagnet (Bi_2Se_3-EuS) Interface
Qi I. Yang, Merav Dolev, Li Zhang +8
Thin films of topological insulator Bi_2Se_3 were deposited directly on insulating ferromagnetic EuS. Unusual negative magnetoresistance was observed near the zero field below the…
