Magnetization dynamics down to zero field in dilute (Cd,Mn)Te quantum wells

Mateusz Goryca, David Ferrand, Piotr Kossacki +8

The evolution of the magnetization in (Cd,Mn)Te quantum wells after a short pulse of magnetic field was determined from the giant Zeeman shift of spectroscopic lines. The dynamics…

Interlayer coupling in EuS/SrS, EuS/PbSe and EuS/PbTe magnetic semiconductor superlatices

H. Kepa, C. F. Majkrzak, A. Sipatov +3

Neutron reflectivity studies of EuS/SrS, EuS/PbSe, and EuS/PbTe all-semiconductor superlattices were carried out in search for exchange interlayer coupling. A relatively weak antif…

Optical alignment and polarization conversion of neutral exciton spin in individual InAs/GaAs quantum dots

K. Kowalik, O. Krebs, A. Lemaître +2

We investigate exciton spin memory in individual InAs/GaAs self-assembled quantum dots via optical alignment and conversion of exciton polarization in a magnetic field. Quasiresona…
