Resistivity ofLa1.825Sr0.175CuO4andYBa2Cu3O7to 1100 K: Absence of saturation and its implications
Abstract
Resistivity was measured from ${T}_{c}$ to 1100 K for ${\mathrm{La}}_{1.825}$${\mathrm{Sr}}_{0.175}$${\mathrm{CuO}}_{4}$, where it is linear to 1100 K, and for ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$, where it is linear to 600 K, increases faster than linear at T>600 K because of loss of oxygen, and changes slope at the 950-K structural transition. The observed absence of saturation in the linear parts of the data implies weak electron-phonon coupling in both superconductors, thus excluding the possibility of phonon-mediated superconductivity. Values of the plasma energy are derived in combination with other experimental data.

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.
