Single-vortex pinning and penetration depth in superconducting NdFeAsO[subscript 1−x]F[subscript x]

Single-vortex pinning and penetration depth in superconducting NdFeAsO[subscript 1−x]F[subscript x]

We use a magnetic force microscope (MFM) to investigate single-vortex pinning and penetration depth in NdFeAsO[subscript 1−x]F[subscript x], one of the highest-T[subscript c] iron-based superconductors. In fields up to 20 G, we observe a disordered vortex arrangement, implying that the pinning force...
