Infrared properties of Sr(Fe,Ni)2As2 superconducting single crystals.

ORAL

Abstract

We report on temperature dependence of the bulk single crystal reflectivity and transmission of thin crystals of iron pnictides Sr(Fe,Ni)$_2$As$_2$ in the broad frequency range from far infrared to UV. We will discuss our data in comparison to results of other experiments and theory.
