Deskripsi
Despite a significant amount of research, there are still many unknowns about the underlying mechanisms of the superconductivity in Fe-based superconductors, in particular the roles of magnetism and nematicity. Here, the authors investigate the compositional dependence of the nematic susceptibility in Fe1+yTe1−xSex and the interplay between nematic and spin fluctuations, as well as the effect of orbital differentiation on nematic instability.
