Magnetoresistance in Co-hBN-NiFe tunnel junctions enhanced by resonant tunneling through single defects in ultrathin hBN barriers
Pablo U. Asshoff, Jose L. Sambricio, Sergey Slizovskiy +7
Hexagonal boron nitride (hBN) is a prototypical high-quality two-dimensional insulator and an ideal material to study tunneling phenomena, as it can be easily integrated in vertica…
Magnetoresistance of vertical Co-graphene-NiFe junctions controlled by charge transfer and proximity-induced spin splitting in graphene
P. U. Asshoff, J. L. Sambricio, A. P. Rooney +9
Graphene is hailed as an ideal material for spintronics due to weak intrinsic spin-orbit interaction that facilitates lateral spin transport and tunability of its electronic proper…
Resonant tunneling spectroscopy of valley eigenstates on a hybrid double quantum dot
T. Kobayashi, J. van der Heijden, M. G. House +6
We report electronic transport measurements through a silicon hybrid double quantum dot consisting of a donor and a quantum dot. Transport spectra show resonant tunneling peaks inv…
A spintronic source of circularly polarized single photons
Pablo Asshoff, Andreas Merz, Heinz Kalt +1
We present a spintronic single photon source which emits circularly polarized light, where the helicity is determined by an applied magnetic field. Photons are emitted from an InGa…
Vortex states in patterned exchange biased NiO/Ni samples
Pablo Asshoff, Katharina Theis-Bröhl, Oleg Petracic +1
We investigated the magnetization reversal of arrays of exchange biased NiO/Ni squares with superconducting quantum interference device magnetometry and micromagnetic simulations.…
