Momentum resolved spin dynamics of bulk and surface excited states in the topological insulator
C. Cacho, A. Crepaldi, M. Battiato +16
The prospective of optically inducing a spin polarized current for spintronic devices has generated a vast interest in the out-of-equilibrium electronic and spin structure of topol…
Electric field-induced Skyrmion distortion and giant lattice rotation in the magnetoelectric insulator Cu2OSeO3
J. S. White, K. Prša, P. Huang +9
Uniquely in Cu2OSeO3, the Skyrmions, which are topologically protected magnetic spin vortex-like objects, display a magnetoelectric coupling and can be manipulated by externally ap…
Anomalous High-Energy Electronic Interaction in Iron-Based Superconductor
D. V. Evtushinsky, A. N. Yaresko, V. B. Zabolotnyy +11
Strong electron interactions in solids increase effective mass, and shrink the electronic bands [1]. One of the most unique and robust experimental facts about iron-based supercond…
Orbital textures and charge density waves in transition metal dichalcogenides
T. Ritschel, J. Trinckauf, K. Koepernik +6
Low-dimensional electron systems, as realized naturally in graphene or created artificially at the interfaces of heterostructures, exhibit a variety of fascinating quantum phenomen…
Unusual Shubnikov-de Haas oscillations in BiTeCl
C. Martin, A. V. Suslov, S. Buvaev +5
We report measurements of Shubnikov-de Haas (SdH) oscillations in single crystals of BiTeCl at magnetic fields up to 31 T and at temperatures as low as 0.4 K. Two oscillation frequ…
Optical properties of BiTeBr and BiTeCl
A. Akrap, J. Teyssier, A. Magrez +4
We present a comparative study of the optical properties - reflectance, transmission and optical conductivity - and Raman spectra of two layered bismuth-tellurohalides BiTeBr and B…
