“…Given that in KFe 2 As 2 bulk superconductivity is observed up to at least P ≃ 6 GPa [10], we conclude that for P > 1.8 GPa bulk magnetism and bulk superconductivity coexist within the whole sample volume. Note that a similar type of bulk coexistence between the antiferromagnetic order and superconductivity was previously reported for various compounds belonging to the so-called 11 [29][30][31][32][33][34][35], 122 [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51], 1144 [52][53][54][55], and 21311 [56] families of Fe-SC's.…”

The magnetic properties of iron-based superconductors AFe2As2 (A =K, Cs, and Rb), which are characterized by the V-shaped dependence of the critical temperature (Tc) on pressure (P ) were studied by means of the muon spin rotation/relaxation technique. In all three systems studied the magnetism was found to appear for pressures slightly below the critical one (Pc), i.e. at pressure where Tc(P ) changes the slope. Rather than competing, magnetism and superconductivity in AFe2As2 are coexisting at P Pc pressure region. Our results support the scenario of a transition from one pairing state to another, with different symmetries on either side of Pc.

Topological magnetic order and superconductivity in EuRbFe4As4

We study single crystals of the magnetic superconductor EuRbFe 4 As 4 by magnetization, electron spin resonance (ESR), angle-resolved photoemission spectroscopy, and electrical resistance in pulsed magnetic fields up to 63 T. The superconducting state below 36.5 K is almost isotropic and is only weakly affected by the development of Eu 2+ magnetic order at 15 K. On the other hand, for the external magnetic field applied along the c axis the temperature dependence of the ESR linewidth reveals a Berezinskii-Kosterlitz-Thouless topological transition below 15 K. This indicates that Eu 2+ planes are a good realization of a two-dimensional XY magnet, which reflects the decoupling of the Eu 2+ magnetic moments from superconducting FeAs layers.

We study single crystals of the magnetic superconductor EuRbFe4As4 by magnetization, electron spin resonance (ESR), angle-resolved photoemission spectroscopy (ARPES) and electrical resistance in pulsed magnetic fields up to 630 kOe. The superconducting state below 36.5 K is almost isotropic and only weakly affected by the development of Eu 2+ magnetic order at 15 K. On the other hand, for the external magnetic field applied along the c-axis the temperature dependence of the ESR linewidth reveals a Berezinskii-Kosterlitz-Thouless topological transition below 15 K. This indicates that Eu 2+ -planes are a good realization of a two-dimensional XY-magnet, which reflects the decoupling of the Eu 2+ magnetic moments from superconducting FeAs-layers.
