Role of CuO chains in vortex core structure in YBa2Cu3O{7-delta}
arXiv:0708.3093 · doi:10.1103/PhysRevB.77.024514
Abstract
The Bogoliubov-deGennes equations are solved for a proximity model for YBa_2Cu_3O_{7-δ} in a magnetic field. The model explicitly includes the effects of the one-dimensional CuO chains, whose influence on the vortex core structure is studied. The rapid vortex core contraction as a function of field which is seen experimentally at low magnetic fields is naturally explained by the presence of the chains.
