Polarized neutron determination of the magnetic excitations inYBa2Cu3O7
Abstract
Polarization analysis has been used to identify the magnetic excitations in ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$. The dominant feature in the spectra is a peak at the (\ensuremath{\pi},\ensuremath{\pi}) reciprocal lattice position and centered at 41 meV. The behavior of the peak is shown to change dramatically at ${\mathit{T}}_{\mathit{c}}$, so that the magnetic excitations responsible for the peak must be strongly coupled to the superconductivity. Below an energy of about 35 meV, superconductivity suppresses the continuum scattering found in addition to the 41-meV peak.

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.
