Magnetic pair-breaking effects: Moment formation and critical doping level in superconductingLa1.85Sr0.15Cu1−xAxO4systems (A=Fe,Co,Ni,Zn,Ga,Al)
Abstract
We have conducted a systematic study on the effect of Cu-site doping in ${\mathrm{La}}_{1.85}$${\mathrm{Sr}}_{0.15}$${\mathrm{CuO}}_{4}$ system. The relations between ${\mathit{T}}_{\mathit{c}}$ and doping level as well as the critical doping levels ${\mathit{x}}_{\mathit{c}}$ have been determined accurately for the Fe-, Co-, Ni-, Zn-, Ga-, and Al-doped systems. Every dopant either carries an intrinsic magnetic moment or induces a net moment on the Cu-${\mathrm{O}}_{2}$ plane. The size of the moment is correlated with the suppression of superconductivity, consistent with the magnetic-pair-breaking effect. The ground states of the dopants have also been determined.

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.
