Breakdown of the critical state in the ferromagnetic superconductor EuFe $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$

William Robert Fern, Joseph Alec Wilcox, Tong Ren +3

There are very few materials in which ferromagnetism coexists with superconductivity due to the destructive effect of the magnetic exchange field on singlet Cooper pairs. The iron-…

Magnetically-controlled Vortex Dynamics in a Ferromagnetic Superconductor

Joseph Alec Wilcox, Lukas Schneider, Estefani Marchiori +11

Ferromagnetic superconductors are exceptionally rare because the strong ferromagnetic exchange field usually destroys singlet superconductivity. EuFe $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$ , an i…
