High-pressure x-ray absorption and diffraction study of the self-doped superconductor EuFBiS2
2020
Physical review B
The BiS 2 -based layered materials are characterized by a highly susceptible physical state, revealing a large response to external conditions. A particular case is the EuFBiS 2 compound, showing a superconducting transition temperature T c ∼ 0.3 K at ambient pressure. Upon increasing external pressure, T c goes through a large amplification, accompanied by a structural phase transition (SPT) from tetragonal to monoclinic symmetry. Here, we use a combination of Eu L 3 -edge x-ray absorption
