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…
Disorder effects in electronic structure of substituted transition metal compounds
D. D. Sarma, A. Chainani, S. R. Krishnakumar +9
Investigating LaNi(1-x)M(x)O3 (M = Mn and Fe), we identify a characteristic evolution of the spectral function with increasing disorder in presence of strong interaction effects ac…
