Abstract

We report our study of the evolution of superconductivity and the phase diagram of the ternary Fe(Se1−xTex)0.82 (0≤x≤1.0) system. We discovered a superconducting phase with Tc,max=14 K in the 0.30.82, which exhibits an incommensurate antiferromagnetic order. We discuss the relationship between the superconductivity and magnetism of this material system in terms of recent results from neutron-scattering measurements. Our results and analyses suggest that superconductivity in this class of Fe-based compounds is associated with magnetic fluctuations and therefore may be unconventional in nature.
