Disorder suppression and precise conductance quantization in constrictions of PbTe quantum wells
G. Grabecki, J. Wrobel, T. Dietl +7
Conductance quantization was measured in submicron constrictions of PbTe, patterned into narrow,12 nm wide quantum wells deposited between PbEuTe barriers. Becaus…

In-plane uniaxial anisotropy rotations in (Ga,Mn)As thin films
M. Sawicki, K-Y. Wang, K. W. Edmonds +9
We show, by SQUID magnetometry, that in (Ga,Mn)As films the in-plane uniaxial magnetic easy axis is consistently associated with particular crystallographic directions and that it…

Unidirectional Transmission of Electrons in a Magnetic Field Gradient
G. Grabecki, J. Wrobel, K. Fronc +7
The work presents an experimental demonstration of time-reversal asymmetry of electron states propagating along boundary separating areas with opposite magnetic fields. For this pu…
