Tuning Inelastic Light Scattering via Symmetry Control in 2D Magnet CrI
Bevin Huang, John Cenker, Xiaoou Zhang +7
The coupling between spin and charge degrees of freedom in a crystal imparts strong optical signatures on scattered electromagnetic waves. This has led to magneto-optical effects w…
Atomically Thin CrCl3: An in-Plane Layered Antiferromagnetic Insulator
Xinghan Cai, Tiancheng Song, Nathan P. Wilson +10
The recent discovery of magnetism in atomically thin layers of van der Waals (vdW) crystals has created new opportunities for exploring magnetic phenomena in the two-dimensional (2…
Thermal Hall Effect Induced by Magnon-Phonon Interactions
Xiaoou Zhang, Yinhan Zhang, Satoshi Okamoto +1
We propose a new mechanism for the thermal Hall effect in exchange spin-wave systems, which is induced by the magnon-phonon interaction. Using symmetry arguments, we first show tha…
Giant Tunneling Magnetoresistance in Spin-Filter van der Waals Heterostructures
Tiancheng Song, Xinghan Cai, Matisse Wei-Yuan Tu +12
Magnetic multilayer devices that exploit magnetoresistance are the backbone of magnetic sensing and data storage technologies. Here we report novel multiple-spin-filter magnetic tu…
Ligand-field helical luminescence in a 2D ferromagnetic insulator
Kyle L. Seyler, Ding Zhong, Dahlia R. Klein +11
Bulk chromium triiodide (CrI) has long been known as a layered van der Waals ferromagnet. However, its monolayer form was only recently isolated and confirmed to be a truly two…
Optical Selection Rule of Excitons in Gapped Chiral Fermion Systems
Xiaoou Zhang, Wen-Yu Shan, Di Xiao
We show that the exciton optical selection rule in gapped chiral fermion systems is governed by their winding number , a topological quantity of the Bloch bands. Specifically, i…
Experimental evidence and control of the bulk-mediated intersurface coupling in topological insulator Bi2Te2Se nanoribbons
Zhaoguo Li, Ion Garate, Jian Pan +14
Nearly a decade after the discovery of topological insulators (TIs), the important task of identifying and characterizing their topological surface states through electrical transp…
