Magnetic excitations and magnetic structure of EuRbFe 4 As 4 were investigated by inelastic
neutron scattering (INS), neutron diffraction, and random phase approximation (RPA) …

The intrinsically hole-doped RbEuFe 4 As 4 exhibits bulk superconductivity at T sc= 36.5 K
and ferromagnetic ordering in the Eu sublattice at T m= 15 K. Here we present a hole …

The ground-state magnetic structure of EuNi 2 As 2 was investigated by single-crystal
neutron diffraction. At base temperature, the Eu 2+ moments are found to form an …

Field-induced superconductivity is a rare phenomenon where an applied magnetic field
enhances or induces superconductivity. Here, we use applied stress as a control switch …

Materials with exceptional magnetism and superconductivity usually conceive emergent
physical phenomena. Here, we investigate the physical properties of the (Eu, La) FeAs2 …

Of all parent compounds of iron-based high-temperature superconductors, EuFe 2 As 2
exhibits by far the largest magnetostructural coupling due to the sizable biquadratic …

We report Eu 153, As 75, and Co 59 nuclear magnetic resonance (NMR) results on EuCo 2
As 2 single crystal. Observations of Eu 153 and As 75 NMR spectra in zero magnetic field at …

Superconductivity in high-temperature superconductors such as cuprates or iron pnictides is
typically achieved by hole or electron doping and it is of great interest to understand how …

Understanding the interplay between superconductivity and magnetism has been a
longstanding challenge in condensed matter physics. Here we report high pressure studies …

Europium-based materials are highly attractive due to their diverse range of physical
properties. In these studies, we aimed to synthesize single crystals of the potentially …
