TL;DR
This study investigates the doping dependence of muSR lineshapes in YBa2Cu3Oy crystals, providing strong evidence for antiferromagnetism in vortex cores at specific doping levels, with comprehensive analysis across related compounds.
Contribution
It offers new insights into the magnetic properties of vortex cores in high-Tc cuprates, supported by extensive experimental data and analysis.
Findings
Evidence of antiferromagnetism in vortex cores at y=6.0
Doping-dependent changes in muSR lineshape observed
Comparison with La2-xSrxCuO4 enhances understanding of magnetic phases
Abstract
This paper has been withdrawn by the authors, because of results obtained from a more exhaustive study of both YBa_2Cu_3O_y and La_{2-x}Sr_xCuO_4 (see cond-mat/0610051).
