Abstract

Motivated by the possible connection between superconductivity in the newly discovered oxide superconductors and the magnetic behavior of these materials, we have carried out numerical simulations to determine the sublattice magnetization ${m}^{\mathrm{\ifmmode^\circ\else\textdegree\fi{}}}$ in the ground state of the spin-(1/2 antiferromagnet on the square lattice with nearest-neighbor interactions. Lattices with N=L\ifmmode\times\else\texttimes\fi{}L spins, where L\ensuremath{\le}12, were used. Extrapolating our results for rotationally invariant correlation functions to the thermodynamic limit, we obtain a much smaller value than obtained previously by exact diagonalization on lattices with sizes up to N=16. For the staggered magnetization, we find ${m}^{\mathrm{\ifmmode^\circ\else\textdegree\fi{}}}$=0.30\ifmmode\pm\else\textpm\fi{}0.02 in units where the saturation value is (1/2. This agrees with the result of spin-wave theory and a recent reanalysis of the perturbation expansion away from the Ising limit.

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.
