Abstract
Superconducting quantum interference device microscopy shows stripes of increased diamagnetic susceptibility in the superconducting state of twinned, orthorhombic, underdoped crystals of Ba(Fe1−xCox)2As2, but not in tetragonal overdoped crystals. These stripes are consistent with enhanced superfluid density on twin boundaries.
