ABSTRACT
We synthesized a superconducting system of FeTe1-xSx with a PbO-type structure. It has the simplest crystal structure among iron-based superconductors. The superconducting transition temperature is about 10 K when x is 0.2. The upper critical field Bc2(0) was estimated to be ~70 T. The coherent length was calculated to be ~2.2 nm. Since FeTe1-xSx is composed of nontoxic elements, this material is a candidate for applications that will further advance research on iron-based superconductors.

    By interpreting various experimental data for the new high temperature FeAs type superconductors in terms of lattice mediated multigap superconductivity, it is shown that these systems strongly resemble MgB2, however, with the distinction that local polaronic lattice effects exist. This fact...

    The emergence of superconductivity in the iron pnictide or cuprate high temperature superconductors usually accompanies the suppression of a long-ranged antiferromagnetic (AFM) order state in a corresponding parent compound by doping or pressurizing. A great deal of effort by doping has been...
