| Electron-phonon coupling is one of the most common interaction in superconducting materials ranging from Nb3Sn, MgB2, iron-based superconductors and high temperature cuprates such as YBa2Cu3O7-δ and HgBa2Ca2Cu3O8+δ. However an importance of the electron-phonon coupling constant, λep, should not be underestimated for characterisation of the electronic properties of superconducting materials, but it is important that the enhanced flux pinning mechanism can be hold responsible for the applicability of the A15 superconducting materials in emerging hydrogen cryomagnetic technology where temperature of the liquid H2 can be as low as 14 K. |
