讨论了强耦合和磁性杂质自旋翻转散射对超导体电磁特性的影响。我们发现，强耦合超导体铅的表面电阻（R s R N）反映声子谱，在频率~ 8× 10−3和11× 10−3 eV附近有特征峰（~ 1.02），在频率~ 22× 10−3 eV附近有一个小的下降（~ 0.95）。广泛的计算电导率和表面阻抗的超导体含有磁性杂质在有限温度下，特别是在无间隙区域，被描述。
The effects of strong coupling and of spin-flip scattering by magnetic impurities on the electromagnetic properties of superconductors are discussed. We have found that the surface resistance (R s R N) of lead, a strong-coupling superconductor, reflects the phonon spectrum and has characteristic peaks (∼ 1.02) near frequencies∼ 8× 10− 3 and 11× 10− 3 eV, and has a small dip (∼ 0.95) near frequency∼ 22× 10− 3 eV. Extensive calculations of the conductivity and surface impedance for superconductors containing magnetic impurities at finite temperatures, especially in the gapless region, are described.
