Effects of Spin Polarization on Electron Transport in Modulation Doped Cd(1-x)Mn(x)Te/Cd(1-y)Mg(y)Te:I Heterostructures
T. Andrearczyk, J. Jaroszynski, G. Karczewski +6
We examine and identify magnetoresistance mechanisms in 2D system containing a sizable concentration of magnetic ions. We argue that some of these mechanisms can serve as a tool to…
The ArDM experiment
ArDM Collaboration, C. Amsler, A. Badertscher +51
The aim of the ArDM project is the development and operation of a one ton double-phase liquid argon detector for direct Dark Matter searches. The detector measures both the scintil…
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…
Quantum ballistic transport in constrictions of n-PbTe
G. Grabecki, J. Wrobel, T. Dietl +7
Conductance of submicron constrictions of PbTe:Bi was studied up to 8T and between 4.2K and 50mK. The structures were fabricated by electron beam lithography and chemical etching o…
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…
Stretching magnetism with an electric field in a nitride semiconductor
D. Sztenkiel, M. Foltyn, G. P. Mazur +11
By direct magnetization measurements, performed employing a new detection scheme, we demonstrate an electrical control of magnetization in wurtzite (Ga,Mn)N. In this dilute magneti…
