Optical Cooling of Nuclear Spins in a CdTe/CdZnTe Quantum Well: The Impact of Kinetic Local Fields on Cooling Efficiency
V. M. Litvyak, P. S. Bazhin, R. André +1
The efficiency of optical cooling of nuclear spins in a CdTe/CdZnTe quantum well is investigated as a function of an external magnetic field. Our results confirm that there is inde…
Kerr effect induced by exchange interaction of electrons separated by a tunnel barrier in a double quantum well
V. K. Kalevich, K. V. Kavokin, M. M. Afanasiev +4
In a structure with two tunnel-coupled quantum wells of different widths, the spin dynamics resulting from resonant pulsed optical pumping of the narrow-well exciton includes the w…
Nuclear spin-spin interactions in CdTe probed by zero and ultra-low-field optically detected NMR
V. M. Litvyak, P. Bazhin, R. André +2
Nuclear magnetic resonance (NMR) is particularly relevant for studies of internuclear spin coupling at zero and ultra-low fields (ZULF), where spin-spin interactions dominate over…
Local field of spin-spin interactions in the nuclear spin system of n-GaAs
V. M. Litvyak, R. V. Cherbunin, V. K. Kalevich +1
At low lattice temperatures the nuclear spins in a solid form a closed thermodynamic system that is well isolated from the lattice. Thermodynamic properties of the nuclear spin sys…
Trion magnetic polarons in (Cd,Mn)Te/(Cd,Mn,Mg)Te quantum wells
F. Godejohann, R. R. Akhmadullin, K. V. Kavokin +7
A trion magnetic polaron formed by the exchange interaction of a positively charged exciton (trion) with localized spins of Mn ions is found experimentally in a 4\,nm wide C…
Unveiling the electron-nuclear spin dynamics in an n-doped InGaAs epilayer by spin noise spectroscopy
C. Rittmann, M. Yu. Petrov, A. N. Kamenskii +6
We discuss the implications of a small indium content (3%) in a GaAs epilayer on the electron- and nuclear-spin relaxation due to enhanced quadrupolar effects induced by the strain…
