Unusual nodal behaviors of the superconducting gap in the iron-based superconductor Ba(Fe${}_{0.65}$Ru${}_{0.35}$)${}_2$As${}_2$: Effects of spin-orbit coupling

L. Liu, K. Okazaki, T. Yoshida +22

We have investigated the superconducting gap of optimally doped Ba(Fe${}_{0.65}$Ru${}_{0.35}$)${}_2$As${}_2$ by angle-resolved photoemission spectroscopy (APRES) using bulk-sensitive 7 eV…
