Interval identification of FMR parameters for spin reorientation transition in (Ga,Mn)As
M. W. Gutowski, W. Stefanowicz, O. Proselkov +3
In this work we report results of ferromagnetic resonance studies of a 6% 15 nm (Ga,Mn)As layer, deposited on (001)-oriented GaAs. The measurements were performed with in-plane ori…
Semiconductor quantum ring as a solid-state spin qubit
Elzbieta Zipper, Marcin Kurpas, Janusz Sadowski +1
The implementation of a spin qubit in a quantum ring occupied by one or a few electrons is proposed. Quantum bit involves the Zeeman sublevels of the highest occupied orbital. Such…
Transport through (Ga,Mn)As nanoislands: Coulomb-blockade and temperature dependence of the conductance
Markus Schlapps, Teresa Lermer, Stefan Geissler +5
We report on magnetotransport measurements of nanoconstricted (Ga,Mn)As devices showing very large resistance changes that can be controlled by both an electric and a magnetic fiel…
Electron-electron interaction in 2D and 1D ferromagnetic (Ga,Mn)As
Daniel Neumaier, Markus Schlapps, Ursula Wurstbauer +4
We investigated the magnetotransport in high quality ferromagnetic (Ga,Mn)As films and wires. At low temperature the conductivity decreases with decreasing temperature without satu…
All-electrical measurement of spin injection in a magnetic - junction diode
Peifeng Chen, Juergen Moser, Philipp Kotissek +4
Magnetic - junction diodes are fabricated to investigate spin-polarized electron transport. The injection of spin-polarized electrons in a semiconductor is achieved by drivin…
