Title: Superconducting and magnetic phase diagram of RbEuFe 4 As 4 and CsEuFe 4 As 4 at high pressure

Abstract

The recently discovered (Rb,Cs)EuFe 4As 4 compounds exhibit an unusual combination of superconductivity ( T c~35K) and ferromagnetism ( T m~15K). We have performed a series of x-ray diffraction, ac magnetic susceptibility, dc magnetization, and electrical resistivity measurements on both RbEuFe 4As 4 and CsEuFe 4As 4 to pressures as high as ~30GPa. We find that the superconductivity onset is suppressed monotonically by pressure while the magnetic transition is enhanced at initial rates of dT m/dP~1.7K/GPa and 1.5K/GPa for RbEuFe 4As 4 and CsEuFe 4As 4, respectively. Near 7 GPa, T c onset and T m become comparable. At higher pressures, signatures of bulk superconductivity gradually disappear. Room-temperature x-ray diffraction measurements suggest the onset of a transition from tetragonal (T) to a half-collapsed-tetragonal (hcT) phase at ~10GPa (RbEuFe 4As 4) and ~12GPa (CsEuFe 4As 4). In conclusion, the ability to tune T c and T m into coincidence with relatively modest pressures highlights (Rb,Cs)EuFe 4As 4 compounds as ideal systems to study the interplay of superconductivity and ferromagnetism.
