Topological magnetic order and superconductivity in EuRbFe${}_4$As${}_4$

M. Hemmida, N. Winterhalter-Stocker, D. Ehlers +13

We study single crystals of the magnetic superconductor EuRbFe${}_4$As${}_4$ by magnetization, electron spin resonance (ESR), angle-resolved photoemission spectroscopy (ARPES) and elec…
