Simultaneous measurements of nuclear spin heat capacity, temperature and relaxation in GaAs microstructures
M. Vladimirova, S. Cronenberger, A. Colombier +4
Heat capacity of the nuclear spin system (NSS) in GaAs-based microstructures has been shown to be much greater than expected from dipolar coupling between nuclei, thus limiting the…
Warm-up spectroscopy of quadrupole-split nuclear spins in n-GaAs epitaxial layers
V. M. Litvyak, R. V. Cherbunin, V. K. Kalevich +4
The efficiency of the adiabatic demagnetization of nuclear spin system (NSS) of a solid is limited, if quadrupole effects are present. Nevertheless, despite a considerable quadrupo…
Electron-induced nuclear magnetic ordering in n-type semiconductors
M. Vladimirova, D. Scalbert, M. S. Kuznetsova +1
Nuclear magnetism in n-doped semiconductors with positive hyperfine constant is revisited. Two kinds of nuclear magnetic ordering can be induced by resident electrons in a deeply c…
Nuclear spin-lattice relaxation in p-type GaAs
M. Kotur, R. I. Dzhioev, M. Vladimirova +6
Spin-lattice relaxation of the nuclear spin system in p-type GaAs is studied using a three-stage experimental protocol including optical pumping and measuring the difference of the…
Spin temperature concept verified by optical magnetometry of nuclear spins
M. Vladimirova, S. Cronenberger, D. Scalbert +5
We develop a method of non-perturbative optical control over adiabatic remagnetisation of the nuclear spin system and apply it to verify the spin temperature concept in GaAs microc…
Nuclear spin relaxation in n-GaAs: from insulating to metallic regime
M. Vladimirova, S. Cronenberger, D. Scalbert +7
Nuclear spin relaxation is studied in n-GaAs thick layers and microcavity samples with different electron densities. We reveal that both in metallic samples where electrons are fre…
