Double island Coulomb blockade in (Ga,Mn)As-nanoconstrictions
S. Geißler, S. Pfaller, M. Utz +4
We report on a systematic study of the Coulomb blockade effects in nanofabricated narrow constrictions in thin (Ga,Mn)As films. Different low-temperature transport regimes have bee…
Magnetoresistance of individual ferromagnetic GaAs/(Ga,Mn)As core-shell nanowires
Christian H. Butschkow, Elisabeth Reiger, Stefan Geißler +6
We investigate, angle dependent, the magnetoresistance (MR) of individual self-assembled ferromagnetic GaAs/(Ga,Mn)As core-shell nanowires at cryogenic temperatures. The shape of t…
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…
Weak localization in ferromagnetic (Ga,Mn)As nanostructures
D. Neumaier, K. Wagner, S. Geissler +4
We report on the observation of weak localization in arrays of (Ga,Mn)As nanowires at millikelvin temperatures. The corresponding phase coherence length is typically between 100 nm…
