Stripes of increased diamagnetic susceptibility in underdoped superconducting Ba(Fe[subscript 1−x]Co[subscript x])[subscript 2]As[subscript 2] single crystals: Evidence for an enhanced superfluid density at twin boundaries
- Stanford
Superconducting quantum interference device microscopy shows stripes of increased diamagnetic susceptibility in the superconducting state of twinned, orthorhombic, underdoped crystals of Ba(Fe{sub 1-x}Co{sub x}){sub 2}As{sub 2}, but not in tetragonal overdoped crystals. These stripes are consistent with enhanced superfluid density on twin boundaries.
