We show magnetotransport results on Ba(Fe1−xCox)2As2 (0.0⩽x⩽0.13) single crystals. We identify the low-temperature resistance step at 23 K in the parent compound with the onset of filamentary superconductivity (FLSC), which is suppressed by an applied magnetic field in a similar manner to the suppre...
