Optically Pumped NMR Evidence for Finite-Size Skyrmions in GaAs Quantum Wells near Landau Level Fillingν=1
Abstract
The Knight shift $[{K}_{s}(\ensuremath{\nu},T)]$ and spin-lattice relaxation time $[{T}_{1}(\ensuremath{\nu},T)]$ of the ${}^{71}\mathrm{Ga}$ nuclei located in $n$-doped GaAs quantum wells are measured using optically pumped NMR, for Landau level filling $0.66<\ensuremath{\nu}<1.76$ and temperature $1.55<T<20$ K. ${K}_{s}(\ensuremath{\nu})$ [proportional to the electron spin polarization $〈{S}_{z}(\ensuremath{\nu})〉$] drops precipitously on either side of $\ensuremath{\nu}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$, which is evidence that the charged excitations of the $\ensuremath{\nu}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$ ground state are finite-size Skyrmions. For $\ensuremath{\nu}<1$, the data are consistent with a many-body ground state which is not fully spin polarized, with a very small spin excitation gap that increases as $\ensuremath{\nu}\ensuremath{\rightarrow}\frac{2}{3}$.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
