• Study of superconductivity in rhodium

Superconducting behavior of the fragile, pure, sub-milli-Kelvin temperature superconductor rhodium has been studied. Rhodium, a paramagnetic transition element, having a free electron density, more than an order of magnitude larger (6.5×10$^{23}$ 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 showsthe 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.
