Schlapps, Markus and Lermer, Teresa and Geissler, Stefan and Neumaier, Daniel and Sadowski, Janusz and Schuh, Dieter and Wegscheider, Werner and Weiss, Dieter (2009) Transport through (Ga,Mn)As nanoislands: Coulomb blockade and temperature dependence of the conductance. Physical Review B (PRB) 80 (12), p. 125330.
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 field. Based on the bias voltage and temperature-dependent measurements down to the millikelvin range we compare the models currently used to describe transport through (Ga,Mn)As nanoconstrictions. We provide an explanation ...
