We have investigated the effect of atomic substitutions in the FeSe system, which exhibits the simplest crystal structure among the iron-based superconductors. An enhancement of the superconducting transition temperature T c was observed with the substitution of S or Te for Se; the T c increased with S substitution by up to 20%, and also increased with Te substitution up to 75%. In contrast, Co or Ni substitutions for the Fe site significantly suppressed superconductivity. In this work we present a detailed description of the substitution technique employed to determine T c in the FeSe system.

- Superconductivity in iron compounds (2011, background): “…a careful study of Tc in Fe1þ Se with Fe content variation and found that ‘‘stoichiometric’’ Fe1þ Se, when made single phase, has ¼ 0:01 and Tc ¼ 8:5 K, while for ¼ 0:03, Tc is below 0.6 K. Mizuguchi et al. (2009) studied FeSe doping with Te and S on the Se site and Co and Ni on the iron site.”
