Abstracts

EN

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 YBa₂Cu₃O_{7-δ} and HgBa₂Ca₂Cu₃O_{8+δ}. However an importance of the electron-phonon coupling constant, λ_{ep}, 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.
