Proximity-induced spin-orbit coupling in graphene/ Bi1.5Sb0.5Te1.7Se1.3 heterostructures / Jafarpisheh, S. (Peter Grünberg Institute) ; Cummings, Aron (Institut Català de Nanociència i Nanotecnologia) ; Watanabe, Kenji (National Institute for Material Science (Tsukuba, Japan)) ; Taniguchi, Takashi (National Institute for Material Science (Tsukuba, Japan)) ; Beschoten, Bernd (RWTH Aachen University) ; Stampfer, Cristoph (RWTH Aachen University)
The weak intrinsic spin-orbit coupling in graphene can be greatly enhanced by proximity coupling. Here, we report on the proximity-induced spin-orbit coupling in graphene transferred by hexagonal boron nitride (hBN) onto the topological insulator Bi1. [...]

Spin states protected from intrinsic electron-phonon coupling reaching 100 ns lifetime at room temperature in MoSe₂ / Ersfeld, Manfred (RWTH Aachen University) ; Volmer, Frank (RWTH Aachen University) ; Melo, Pedro Miguel M.

(Université de Liège. Complex and Entangled Systems from Atoms to Materials) ; Beschoten, Bernd (RWTH Aachen University)
We present time-resolved Kerr rotation measurements, showing spin lifetimes of over 100 ns at room temperature in monolayer MoSe. These long lifetimes are accompanied by an intriguing temperature-dependence of the Kerr amplitude, which increases with temperature up to 50 K and then abruptly switches sign. [...]

Magneto-optical study of magnetization reversal asymmetry in exchange bias / Tillmanns, A. (Rheinisch-Westfälische Technische Hochschule Aachen. Institut für physikalisches) ; Oertker, S. (Rheinisch-Westfälische Technische Hochschule Aachen. Institut für physikalisches) ; Beschoten, Bernd (Rheinisch-Westfälische Technische Hochschule Aachen. Institut für physikalisches) ; Güntherodt, G. (Rheinisch-Westfälische Technische Hochschule Aachen. Institut für physikalisches) ; Leighton, C. (University of California, San Diego. Department of Physics) ; Schuller, Ivan K. (University of California, San Diego. Department of Physics) ; Nogués, Josep (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
The asymmetric magnetization reversal in exchange biased Fe/MnF2 involves coherent (Stoner-Wohlfarth) magnetization rotation into an intermediate, stable state perpendicular to the applied field. We provide here the experimentally tested analytical conditions for the unambiguous observation of both longitudinal and transverse magnetization components using the magneto-optical Kerr effect.
