The iron pnictide superconductor family hosts high temperature superconductivity that exists above the predicted temperature limit of BCS theory. EuRbFe4As4, a member of the 1144 family, is a unique example that hosts coexisting superconducting (Tc = 37 K) and ferromagnetic (Tm = 15 K) phases, which results in many interesting behaviors, including a possible pair-density-wave state. In this talk, I will introduce our measurement technique of 2e-ARPES, why it is useful for characterizing unconventional superconductivity, and our measurements of EuRbFe4As4. Particularly, I will highlight evidence for the detection of pairing in this system.
