Hidden spin-orbital texture at the -located valence band maximum of a transition metal dichalcogenide semiconductor
Oliver J. Clark, Oliver Dowinton, Mohammad Saeed Bahramy +1
Finding stimuli capable of driving an imbalance of spin-polarised electrons within a solid is the central challenge in the development of spintronic devices. However, without the a…
Emergence of Fermi arcs and novel magnetic splitting in an antiferromagnet
Benjamin Schrunk, Yevhen Kushnirenko, Brinda Kuthanazhi +14
The Fermi arcs are signatures of exotic states in solids because they defy conventional concept of Fermi surfaces as closed contours in momentum space. Fermi arcs were first discov…
Mn-rich MnSb2Te4: A topological insulator with magnetic gap closing at high Curie temperatures of 45-50 K
S. Wimmer, J. Sánchez-Barriga, P. Küppers +18
Ferromagnetic topological insulators exhibit the quantum anomalous Hall effect that might be used for high precision metrology and edge channel spintronics. In conjunction with sup…
Large magnetic gap at the Dirac point in a Mn-induced BiTe heterostructure
E. D. L. Rienks, S. Wimmer, P. S. Mandal +15
Magnetically doped topological insulators enable the quantum anomalous Hall effect (QAHE) which provides quantized edge states for lossless charge transport applications. The edge…
Anomalous behavior of the electronic structure of (BiIn)Se across the quantum-phase transition from topological to trivial insulator
J. Sánchez-Barriga, I. Aguilera, L. V. Yashina +9
Using spin- and angle-resolved spectroscopy and relativistic many-body calculations, we investigate the evolution of the electronic structure of (BiIn)Se bulk s…
Strong spin dependence of correlation effects in Ni due to Stoner excitations
J. Sánchez-Barriga, R. Ovsyannikov, J. Fink
Using high-resolution angle-resolved photoemission, we observe a strong spin-dependent renormalization and lifetime broadening of the quasiparticle excitations in the electronic ba…
