Quantum effects in magnetotransport of InGaAs quantum wells with remote Mn impurities

Quantum effects in magnetotransport of InGaAs quantum wells with remote Mn impurities

We have studied magnetoresistance and Hall effect of GaAs/InxGa1−xAs quantum wells with remote Mn impurity. Temperature and magnetic field dependencies of samples resistivity indicate several effects related to the magnetic subsystem. Shubnikov - de Haas oscillations indicate the presence of several...
