Magnetic disorder and gap symmetry in optimally electron doped Sr(Fe, Co)${}_2$As${}_2$ superconductor

Luminita Harnagea, Giri Mani, Rohit Kumar +1

We investigate the magnetic pair-breaking due to Mn impurities in the optimally electron doped Sr(Fe${}_{0.88}$Co${}_{0.12}$)${}_2$As${}_2$ superconductor to deduce the symmetry of t…
