Coexistence of Dirac-Cone States and Superconductivity in Iron Pnictide Ba(Fe${}_{1-x}$Ru${}_x$As)${}_2$

Y. Tanabe, K. K. Huynh, S. Heguri +6

The Ru doping effect on the Dirac cone states is investigated in iron pnictide superconductors Ba(Fe${}_{1-x}$Ru${}_x$As)${}_2$ using the transverse magnetoresistance (MR) measurements a…
