The response of the worldwide scientific community to the discovery in 2008 of
superconductivity at T c= 26 K in the Fe-based compound LaFeAsO1− x F x has been very …

Despite decades of intense research, the origin of high-temperature superconductivity in
cuprates and iron-based compounds is still a mystery. Magnetism and superconductivity are …

Among various parent compounds of iron pnictide superconductors, EuFe 2 As 2 stands out
due to the presence of both spin density wave of Fe and antiferromagnetic (AFM) ordering of …

We discover a robust coexistence of superconductivity and ferromagnetism in an iron
arsenide RbEuFe 4 As 4. The new material crystallizes in an intergrowth structure of RbFe 2 …

In the novel stoichiometric iron-based material RbEuFe 4 As 4, superconductivity coexists
with a peculiar long-range magnetic order of Eu 4f states. Using angle-resolved …

We report the discovery of a novel Fe-based superconductor EuAFe4As4 (A= Rb, Cs) and
describe its superconducting properties. EuAFe4As4 has a tetragonal unit cell with a P …

The magnetic structure of the Eu 2+ moments in the superconducting EuFe 2 (As 1− x P x) 2
sample with x= 0.15 has been determined using element-specific x-ray resonant magnetic …

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

We report the measurements of resistivity and magnetization under magnetic fields parallel
and perpendicular to the basal plane, respectively, on a cobalt-doped Eu (Fe 0.89 Co 0.11) …

Magnetic semimetals are very promising for potential applications in novel spintronic
devices. Nevertheless, realizing tunable topological states with magnetism in a controllable …
