Spin-polarized tunneling through randomly transparent magnetic junctions: Reentrant magnetoresistance approaching the Julliere limit
Grigory Tkachov, Klaus Richter
Electron conductance in planar magnetic tunnel junctions with long-range barrier disorder is studied within Glauber-eikonal approximation enabling exact disorder ensemble averaging…
Spin-polarized Quantum Transport in Mesoscopic Conductors: Computational Concepts and Physical Phenomena
Michael Wimmer, Matthias Scheid, Klaus Richter
Mesoscopic conductors are electronic systems of sizes in between nano- and micrometers, and often of reduced dimensionality. In the phase-coherent regime at low temperatures, the c…
Quantum dissipative Rashba spin ratchets
Sergey Smirnov, Dario Bercioux, Milena Grifoni +1
We predict the possibility to generate a finite stationary spin current by applying an unbiased ac driving to a quasi-one-dimensional asymmetric periodic structure with Rashba spin…
Spin currents in rough graphene nanoribbons: Universal fluctuations and spin injection
M. Wimmer, I. Adagideli, S. Berber +2
We investigate spin conductance in zigzag graphene nanoribbons and propose a spin injection mechanism based only on graphitic nanostructures. We find that nanoribbons with atomical…
Zeeman ratchets: pure spin current generation in mesoscopic conductors with non-uniform magnetic fields
Matthias Scheid, Dario Bercioux, Klaus Richter
We consider the possibility to employ a quantum wire realized in a two-dimensional electron gas (2DEG) as a spin ratchet. We show that a net spin current without accompanying net c…
Andreev magnetotransport in low-dimensional proximity structures: Spin-dependent conductance enhancement
Grygoriy Tkachov, Klaus Richter
We study the excess conductance due to the superconducting proximity effect in a ballistic two-dimensional electron system subject to an in-plane magnetic field. We show that under…
