A Four Unit Cell Periodic Pattern of Quasi-Particle States Surrounding Vortex Cores in Bi 2 Sr 2 CaCu 2 O 8+δ
Open accessAbstract
Scanning tunneling microscopy is used to image the additional quasi-particle states generated by quantized vortices in the high critical temperature superconductor Bi 2 Sr 2 CaCu 2 O 8+δ . They exhibit a copper-oxygen bond–oriented “checkerboard” pattern, with four unit cell (4 a 0 ) periodicity and a ∼30 angstrom decay length. These electronic modulations may be related to the magnetic field–induced, 8 a 0 periodic, spin density modulations with decay length of ∼70 angstroms recently discovered in La 1.84 Sr 0.16 CuO 4 . The proposed explanation is a spin density wave localized surrounding each vortex core. General theoretical principles predict that, in the cuprates, a localized spin modulation of wavelength λ should be associated with a corresponding electronic modulation of wavelength λ/2, in good agreement with our observations.

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.
