Protected pseudohelical edge states in proximity graphene ribbons and flakes
Tobias Frank, Petra Högl, Martin Gmitra +2
We investigate topological properties of models that describe graphene on realistic substrates which induce proximity spin-orbit coupling in graphene. A phase diagra…
Magnetoanisotropic Josephson effect due to interfacial spin-orbit fields in superconductor/ferromagnet/superconductor junctions
Andreas Costa, Petra Högl, Jaroslav Fabian
We study theoretically the effects of interfacial Rashba and Dresselhaus spin-orbit coupling in superconductor/ferromagnet/superconductor (S/F/S) Josephson junctions---with allowin…
Trivial and inverted Dirac bands, and emergence of quantum spin Hall states in graphene on transition-metal dichalcogenides
Martin Gmitra, Denis Kochan, Petra Högl +1
Proximity orbital and spin-orbital effects of graphene on monolayer transition-metal dichalcogenides (TMDCs) are investigated from first-principles. The Dirac band structure of gra…
Electric field control of spin lifetimes in Nb-SrTiO by spin-orbit fields
A. M. Kamerbeek, P. Högl, J. Fabian +1
We show electric field control of the spin accumulation at the interface of the oxide semiconductor Nb-SrTiO with Co/AlO spin injection contacts at room temperature. Th…
Magnetoanisotropic Andreev Reflection in Ferromagnet/Superconductor Junctions
Petra Högl, Alex Matos-Abiague, Igor Žutić +1
Andreev reflection spectroscopy of ferromagnet/superconductor (FS) junctions is an important probe of spin polarization. We theoretically investigate spin-polarized transport in FS…
