Unusually weak irradiation effects in anisotropic iron-based superconductor RbCa2Fe4As4F2

Daniele Torsello, Erik Piatti, Michela Fracasso +7

We report on the effects of 3.5 MeV proton irradiation in RbCa${}_2$Fe${}_4$As${}_4$F${}_2$, an iron-based superconductor with unusual properties in between those of the pnictides and of t…
