Visualizing higher-fold topology in chiral crystals
Tyler A Cochran, Ilya Belopolski, Kaustuv Manna +21
Novel topological phases of matter are fruitful platforms for the discovery of unconventional electromagnetic phenomena. Higher-fold topology is one example, where the low-energy d…
Observation of antiphase coherent phonons in the warped Dirac cone of BiTe
E. Golias, J. Sánchez-Barriga
In this Rapid Communication we investigate the coupling between excited electrons and phonons in the highly anisotropic electronic structure of the prototypical topological insulat…
Spin Mapping of Surface and Bulk Rashba States in Ferroelectric a-GeTe(111) Films
H. J. Elmers, R. Wallauer, M. Liebmann +16
A comprehensive mapping of the spin polarization of the electronic bands in ferroelectric a-GeTe(111) films has been performed using a time-of-flight momentum microscope equipped w…
Ultrafast spin polarization control of Dirac fermions in topological insulators
J. Sánchez-Barriga, E. Golias, A. Varykhalov +7
Three-dimensional topological insulators (TIs) are characterized by spin-polarized Dirac-cone surface states that are protected from backscattering by time-reversal symmetry. Contr…
Ferroelectricity and Rashba effect in GeTe
C. Rinaldi, D. Di Sante, A. Giussani +9
GeTe has been proposed as the father compound of a new class of functional materials displaying bulk Rashba effects coupled to ferroelectricity: ferroelectric Rashba semiconductors…
Magnetically induced spin reorientation on the surface of a topological insulator (a surface magnetic topological insulator MBE film)
Su-Yang Xu, M. Neupane, Chang Liu +18
The surface of topological insulators is proposed as a promising platform for spintronics and quantum information applications. In particular, when time- reversal symmetry is broke…
Topological surface state under graphene for two-dimensional spintronics in air
A. Varykhalov, D. Marchenko, M. R. Scholz +3
Spin currents which allow for a dissipationless transport of information can be generated by electric fields in semiconductor heterostructures in the presence of a Rashba-type spin…
Quantitative determination of spin-dependent quasiparticle lifetimes and electronic correlations in hcp cobalt
J. Sanchez-Barriga, J. Minar, J. Braun +13
We report on a quantitative investigation of the spin-dependent quasiparticle lifetimes and electron correlation effects in ferromagnetic hcp Co(0001) by means of spin and angle-re…
Interplay between the magnetic anisotropy contributions of Cobalt nanowires
J. Sanchez-Barriga, M. Lucas, F. Radu +5
We report on the magnetic properties and the crystallographic structure of the cobalt nanowire arrays as a function of their nanoscale dimensions. X-ray diffraction measurements sh…
