Abstract
Antiphase boundaries represent dislocation free interfaces in YBaCuO with s mall structural width of less than 1 nm. We show, that strong pinning at su ch boundaries takes places by quasiparticle scattering induced variation of the condensation energy, characteristic of superconductors with anisotropi c gap. The length scale of the order parameter. suppression at antiphase bo undaries will be discussed.
