已经研究了易碎、纯、亚毫开尔文温度超导体铑的超导行为。铑是一种顺磁性过渡元素，具有比金属单价超导体大一个数量级（6.5×10 23 cm -3 ）以上的自由电子密度，在几百微开尔文（10 -6K)，在环境压力下。铑表现出由残余电子-声子相互作用带来的传统BCS超导性，并表现出I型超导性的特征。在这项工作中，我们研究了铑中电子-声子、电子-电子和电子-顺磁子相互作用的影响。此外，我们评估了与铑相关的各种特征参数。最后，我们得出结论，铑完全由 Bardeen-Cooper-Schrieffer (BCS) 理论解释，该理论从根本上对应于电子-声子相互作用的瞬时性质以及瞬时电子-库仑相互作用和瞬时电子-自旋相互作用。

Study of superconductivity in rhodium
Superconducting behaviour of the fragile, pure, sub-milli-Kelvin temperature superconductor rhodium has been studied. Rhodium, a paramagnetic transition element, having free electron density, more than an order of magnitude larger (6.5×1023 cm−3) than a metallic monovalent superconductor, exhibits superconductivity at an extremely low temperature of a few hundred micro-Kelvin (10−6 K), at ambient pressure. Rhodium exhibits traditional BCS superconductivity brought about by the residual electron–phonon interaction and shows the characteristics of Type-I superconductivity. In this work, we have studied the effect of electron–phonon, electron–electron and electron–paramagnon interactions in rhodium. Further, we have evaluated the various characteristic parameters associated with rhodium. Finally, we conclude that rhodium is explained totally by the Bardeen–Cooper–Schrieffer (BCS) theory which corresponds fundamentally to the instantaneous nature of electron–phonon interaction along with the instantaneous electron–Coulomb interaction and instantaneous electron–spin interaction.
