Magnetic Field Induced Instabilities in Localised Two-Dimensional Electron Systems
M. Baenninger, A. Ghosh, M. Pepper +3
We report density dependent instabilities in the localised regime of mesoscopic two-dimensional electron systems (2DES) with intermediate strength of background disorder. They are…

Field-tunable magnetic phases in a semiconductor-based two-dimensional Kondo lattice
C. Siegert, A. Ghosh, M. Pepper +4
We show the existence of intrinsic localized spins in mesoscopic high-mobility GaAs/AlGaAs heterostructures. Non-equilibrium transport spectroscopy reveals a quasi-regular distribu…

Sensitivity of the magnetic state of a spin lattice on itinerant electron orbital phase
C. Siegert, A. Ghosh, M. Pepper +4
Spatially extended localized spins can interact via indirect exchange interaction through Friedel oscillations in the Fermi sea. In arrays of localized spins such interaction can l…
