Controlling the efficiency of spin injection into graphene by carrier drift
C. Józsa, M. Popinciuc, N. Tombros +2
Electrical spin injection from ferromagnetic metals into graphene is hindered by the impedance mismatch between the two materials. This problem can be reduced by the introduction o…
Nonequilibrium Green's functions approach to strongly correlated few-electron quantum dots
K. Balzer, M. Bonitz, R. van Leeuwen +2
The effect of electron-electron scattering on the equilibrium properties of few-electron quantum dots is investigated by means of nonequilibrium Green's functions theory. The groun…
Superexchange-Driven Magnetoelectricity in Magnetic Vortices
Kris T. Delaney, Maxim Mostovoy, Nicola A. Spaldin
We demonstrate that magnetic vortices in which spins are coupled to polar lattice distortions via superexchange exhibit an unusually large linear magnetoelectric response. We show…
The annealing mechanism of AuGe/Ni/Au ohmic contacts to a two-dimensional electron gas in GaAs/AlGaAs heterostructures
E. J. Koop, M. J. Iqbal, F. Limbach +6
Ohmic contacts to a two-dimensional electron gas (2DEG) in GaAs/AlGaAs heterostructures are often realized by annealing of AuGe/Ni/Au that is deposited on its surface. We studied h…
Magnetoelectric coupling in the cubic ferrimagnet Cu2OSeO3
Jan-Willem G. Bos, Claire V. Colin, Thomas T. M. Palstra
We have investigated the magnetoelectric coupling in the lone pair containing piezoelectric ferrimagnet Cu2OSeO3. Significant magnetocapacitance develops in the magnetically ordere…
Electron energy level statistics in graphene quantum dots
H. De Raedt, M. I. Katsnelson
Motivated by recent experimental observations of size quantization of electron energy levels in graphene quantum dots \cite{ponomarenko} we investigate the level statistics in the…
Collective orbital excitations in orbitally ordered YVO3 and HoVO3
E. Benckiser, R. Rückamp, T. Möller +6
We study orbital excitations in the optical absorption spectra of YVO3 and HoVO3. We focus on an orbital absorption band observed at 0.4 eV for polarization E parallel c. This feat…
Anisotropic spin relaxation in graphene
N. Tombros, S. Tanabe, A. Veligura +4
Spin relaxation in graphene is investigated in electrical graphene spin valve devices in the non-local geometry. Ferromagnetic electrodes with in-plane magnetizations inject spins…
