Universality in the current decay and flux creep of Y-Ba-Cu-O high-temperature superconductors
Abstract
Recent data on flux creep in a variety of Y-Ba-Cu-O superconductors show a temperature-independent plateau in the magnetization decay Sieq-d lnM(t)/d ln(t), with values clustered in the range S=0.020--0.035. This apparent universality in S, which appears at odds with conventional flux-creep theories, can be explained naturally if one assumes the existence of a truly superconducting ordered phase at low temperatures that has a strongly nonlinear (exponential) I-V characteristic.

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.
