Nematic superconducting state in iron pnictide superconductors
Jun Li, Paulo J. Pereira, Jie Yuan +19
Nematic order often breaks the tetragonal symmetry of iron-based superconductors. It arises from regular structural transition or electronic instability in the normal phase. Here,…

Lower critical field and SNS-Andreev spectroscopy of 122-arsenides: Evidence of nodeless superconducting gap
M. Abdel-Hafiez, P. J. Pereira, S. A. Kuzmichev +10
Using two experimental techniques, we studied single crystals of the 122-FeAs family with almost the same critical temperature, Tc. We investigated the temperature dependence of th…
