Interplay Between Magnetism and Superconductivity in EuFe$$_2$$(As$$_{1-x}$$P$$_x$$)$$_2$$ Single Crystals

Electronic Structures and Surface Reconstructions in Magnetic Superconductor RbEuFe4As4

“…11−20 This unique coexistence rapidly became the subject of intensive studies. Novel ferromagnetic superconducting phases, such as the domain Meissner state and domain vortex state, were discovered; 16,18 a peculiar interplay was observed in the microwave response, 19 and a crossover from a dominating superconducting to a dominating ferromagnetic order was reported. 20 The magnetic superconductor RbEuFe 4 As 4 has a more complex structure, alternating Eu-122 and Rb-122 blocks.…”
