研究铁基体系超导电性的一个可能的理论模型

A Possible Theoretical Model For Studying Superconductivity In Fe-based Systems

Ranjan Chaudhury

摘要:

本文提出了一种微观模型的理论方法来解释铁基化合物中所观察到的高温超导性。上述方案考虑了两个重要方面,即(i)接近磁有序的超导转变和(ii)层状结构。从超导转变温度的计算,它表明,在铁基超导体的磁性机制,通过有效的吸引库仑相互作用的费米液体理论的框架内运作,是非常合理的。

英文摘要:

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.
