dc.description.abstractThe superconductivity in the Bi-II phase of elemental bismuth (transition temperature Tc≃3.92 K at pressure p≃2.80 GPa) was studied experimentally by means of the muon-spin rotation as well as theoretically by using the Eliashberg theory in combination with density functional theory calculations. Experiments reveal that Bi-II is a type-I superconductor with a zero temperature value of the thermodynamic critical field Bc(0)≃31.97 mT. The Eliashberg theory approach provides a good agreement with the experimental Tc and the temperature evolution of Bc. The estimated value for the retardation (coupling) parameter kBTc/ωln≈0.07 (ωln is the logarithmically averaged phonon frequency) suggests that Bi-II is an intermediately coupled superconductor.
