Anomalous Hanle Effect in Quantum Dots : Evidence for Strong Dynamical Nuclear Polarization in Transverse Magnetic Field
O. Krebs, P. Maletinsky, T. Amand +5
Hanle effect is ubiquitous in the study of spin-related phenomena and has been used to determine spin lifetime, precession and transport in semiconductors. Here, we report an exper…
Phosphorous alloying: controlling the magnetic anisotropy in ferromagnetic (Ga,Mn)(As,P) Layers
M. Cubukcu, H. J. von Bardeleben, Kh. Khazen +4
Phosphorous alloying of GaMnAs thin films has been used for the manipulation of the magnetic anisotropies in ferromagnetic Ga0.93Mn0.07As1-yPy layers. We have determined the anisot…
Hyperfine interaction in InAs/GaAs self-assembled quantum dots : dynamical nuclear polarization versus spin relaxation
O. Krebs, B. Eble, A. Lemaître +4
We report on the influence of hyperfine interaction on the optical orientation of singly charged excitons X+ and X- in self-assembled InAs/GaAs quantum dots. All measurements were…
Origin of the emission within the cavity mode of coupled quantum dot-cavity systems
J. Suffczynski, A. Dousse, K. Gauthron +6
The origin of the emission within the optical mode of a coupled quantum dot-micropillar system is investigated. Time-resolved photoluminescence is performed on a large number of de…
Optical bistability in a GaAs based polariton diode
Daniele Bajoni. Elizaveta Semenova, Aristide Lemaître, Sophie Bouchoule +5
We report on a new type of optical nonlinearity in a polariton p-i-n microcavity. Abrupt switching between the strong and weak coupling regime is induced by controlling the electri…
Field-Driven Domain-Wall Dynamics in GaMnAs Films with Perpendicular Anisotropy
Alexandre Dourlat, Vincent Jeudy, Aristide Lemaître +1
We combine magneto-optical imaging and a magnetic field pulse technique to study domain wall dynamics in a ferromagnetic (Ga,Mn)As layer with perpendicular easy axis. Contrary to u…
