ResumoSuperconducting quantum interference device microscopy shows stripes of increased diamagnetic susceptibility in the superconducting state of twinned, orthorhombic, underdoped crystals of $\text{Ba}{({\text{Fe}}_{1\ensuremath{-}x}{\text{Co}}_{x})}_{2}{\text{As}}_{2}$, but not in tetragonal overdoped crystals. These stripes are consistent with enhanced superfluid density on twin boundaries.
