Superconductivity in Sr(Fe,Ni)$_2$As$_2$ single crystals

ORAL

Abstract

Iron pnictide compounds are the subject of intense research efforts because of their relatively high superconducting critical temperatures and the interplay of magnetic, structural, and superconducting phases found in these materials. Of the known superconducting iron pnictide compounds, those with the ThCr$_2$Si$_2$ structure appear to have the best chemical homogeneity. We present transport, magnetic, and specific heat measurements of Ni-substituted SrFe$_2$As$_2$ flux-grown single crystals.
