Observation of single-quantum vortex splitting in the Ba${}_{1-x}$K${}_x$Fe${}_2$As${}_2$ superconductor

Q. Z. Zhou, B. R. Chen, B. K. Xiang +12

Since their theoretical discovery more than a half-century ago, vortices observed in bulk superconductors have carried a quantized value of magnetic flux determined only by fundame…
