The possible existence of a sign-changing gap symmetry in BaFe 2 As 2 -derived superconductors (SC) has been an exciting topic of research in the last few years. To further investigate this subject we combine Electron Spin Resonance (ESR) and pressure-dependent transport measurements to investigate...
