Abstract

A theoretical approach with a microscopic model is proposed for the observed "high temperature superconductivity" in the Iron-based compounds. The above scheme takes into account two important aspects viz. (i) superconducting transition close to magnetic ordering and (ii) the layered structure. From the calculation of the superconducting transition temperature, it is shown that in the Fe-based superconductors the magnetic mechanism for superconductivity, operating through the effective attractive Coulomb interaction within the framework of the Fermi Liquid theory, is highly plausible.
